How to Build Your First Commander Deck: A Complete Bello Example

Updated September 3, 2026; the complete product list, card text, printings, and Commander legality were rechecked against Wizards and Scryfall that day.

Choose the deck’s job before choosing its noncommander cards. A useful first Commander deck answers one question in a sentence: what will this deck do repeatedly before it wins? Then its remaining library cards (99 with one commander or 98 with a legal pair) provide lands, mana, card flow, interaction, and enough plan pieces to make that sentence happen.

This guide applies the framework to Animated Army, the official red-green Bloomburrow Commander deck led by Bello, Bard of the Brambles. Wizards’ complete decklist↗ (opens in a new tab) expands to exactly 100 cards. Rather than pretending a made-up shell is complete, the worked example counts that real list, assigns every slot one primary role, identifies all 19 commander targets, and follows one legal opening sequence.

Step 1: turn the commander into one sentence

Bello, Bard of the Brambles costs {1}{R}{G}. During your turn, every non-Equipment artifact and non-Aura enchantment you control with mana value 4 or greater is also a 4/4 Elemental creature with indestructible, haste, and a trigger that draws a card when it deals combat damage to a player.

That text produces the completed plan sentence:

Cast mana-value-four-or-greater artifacts and enchantments, let Bello turn them into hasty 4/4 attackers, draw when they connect, then finish by multiplying combat damage or attacking with several animated permanents.

“Artifacts and enchantments” is only a theme. The mana-value threshold, exclusions, attack timing, and combat-damage draw are the actual plan. Equipment and Auras do not qualify. A three-mana artifact does not qualify. An eligible permanent is animated only during its controller’s turn.

The commander’s red-green color identity permits red, green, colorless, and land cards whose color identity stays within those colors. Color identity includes mana symbols in rules text, color indicators, and characteristic-defining abilities, not only the symbols in the upper-right cost. With two commanders, use their combined identities. One commander leaves 99 cards for the library; a legal paired-commanders deck leaves 98.

Step 2: count the real 100-card shell

The official list has 84 distinct entries because its basic lands appear in multiples. Expanding those quantities yields this disjoint primary-role inventory:

Primary role	Cards	What was counted there
Commander	1	Bello
Lands	38	18 basics and 20 nonbasics
Mana development and reducers	21	Permanent sources, land ramp, temporary mana, and one reducer
Card flow and selection	11	Draw, play-from-library effects, and selection
Interaction	7	Targeted answers and creature sweepers
Plan, payoff, protection, and finish	22	Remaining cards that create or multiply the deck’s attack plan
Total	100	Every physical card counted once

Several cards perform more than one job. The primary-role rule keeps the total honest. A mana artifact that Bello can animate remains in the mana category if producing mana is its first job. An enchantment that draws cards remains in card flow even though it can attack. Overlap is strength; it is not permission to count one card three times.

The curve across all 62 nonlands, including Bello, is:

Mana-value band	Cards
1-3	26
4-5	25
6+	11

Eleven cards at 6 or more is a real top end. That explains the 38 lands and unusually deep mana-development category. It also warns a new pilot not to keep a speculative two-land hand just because the deck contains many rocks.

Step 3: verify the commander’s complete target inventory

Animated Army contains exactly 19 artifacts or enchantments that meet Bello’s mana-value threshold: seven at 4, six at 5, four at 6, and two at 7. These are the engine’s complete stock target set, not a handful of generic examples.

The seven four-mana targets

The six five-mana targets

The six targets at six or seven mana

Bello supplies haste, so a qualifying permanent cast during the main phase can attack that turn. Bello also supplies indestructible only during your turn. That protects the animated attacker from ordinary destruction in combat, but it does not protect Bello, stop exile, or make the permanent indestructible during an opponent’s turn.

Step 4: make the mana serve the threshold

The first-draft worksheet suggests about ten ramp cards, but Animated Army assigns 21 slots to mana development and reducers. That is not automatically excessive. The list has 25 cards in the four-to-five band, 11 at six or more, and a commander that specifically wants substantial permanents.

The low-cost foundation includes artifacts and land ramp that work before the target permanents arrive.

• 

• 

• 

The three qualifying mana artifacts shown in the target inventory serve twice: they produce mana after resolving and become 4/4 attackers during your turn while Bello is present. Their printed mana values remain 4 or 5 even if a reducer changes the amount paid. A reducer is not a mana source and cannot pay an activated ability, so it stays separately labeled within the 21-card category.

The practical result is 38 lands plus 21 mana-development cards, not a recommendation to copy 59 mana-related slots into every first deck. Many of the 21 overlap with draw, attackers, or the commander’s threshold. Keep 38 for the first games; change the count only after recording missed land drops or excess lands.

Step 5: separate card advantage from selection

The stock primary-role audit assigns 11 cards to card flow and selection. Those labels are not interchangeable:

• Card advantage increases usable cards in hand or grants additional cards that can be played or cast.
• Selection changes which card is available without necessarily increasing card count.
• Recursion recovers a spent card and should be labeled by what it can actually return.

The target inventory already shows several engines. Two more stock examples make the distinction clear.

• 

• 

Bello itself is card flow only when an animated permanent connects with a player. Four eligible attackers do not guarantee four cards: blockers, removal, prevention, and failed attacks matter. Count cards actually drawn after games rather than counting every possible trigger during deck construction.

Step 6: confirm interaction by coverage

The seven-card primary interaction inventory covers broad permanents, artifacts, creatures, and creature-heavy boards. Each effect still has a specific limitation.

• 

• 

• 

• 

• 

• 

The seventh interaction card, Spine of Ish Sah, is already in the seven-mana target gallery. That overlap is valuable: it answers a permanent, becomes a Bello attacker on your turn, and returns to hand if it goes from the battlefield to the graveyard. It is still a seven-mana answer, so the cheaper six remain necessary.

Step 7: prove one legal opening line

A worked line exposes whether the plan is only words. This one uses only verified stock cards and assumes the listed cards are in hand:

1. Turn one: play a Forest and cast Sol Ring.
2. Turn two: play a Mountain; spend green, red, and one colorless to cast Bello.
3. Turn three: play a third land. The three lands plus Sol Ring provide at least four mana, enough to cast Outpost Siege.
4. During that turn, Bello makes the Siege a 4/4 Elemental creature with haste and indestructible.
5. Attack with the animated Siege. If it deals combat damage to a player, Bello’s granted trigger draws one card.

The draw is conditional on connecting. The line also reveals why colored lands remain essential: Sol Ring supplies the generic mana but cannot produce either colored symbol in Bello’s cost.

With Berserkers’ Onslaught already on the battlefield, an animated permanent with double strike can deal combat damage in both combat-damage steps and trigger the granted draw ability each time it connects. With Gratuitous Violence or Unnatural Growth, the same 4/4 attackers become a faster clock. Those are real ways the stock list converts its engine into a finish.

The completed first-deck decision

For a new pilot starting with this subject, the finished first draft is the official 100 unchanged:

Decision	Completed value
Commander	Bello, Bard of the Brambles
Color identity	Red-green
Plan	Animate qualifying artifacts and enchantments, attack, draw, and multiply combat damage
Cards	100
Lands	38
Mana development/reducers	21
Card flow/selection	11
Interaction	7
Plan/payoff/protection/finish	22
Nonland curve	26 at 1-3 / 25 at 4-5 / 11 at 6+
Qualifying Bello targets	19: 7 at MV4 / 6 at MV5 / 4 at MV6 / 2 at MV7
First revision	None before five recorded games

That last line matters. Building a first deck does not require replacing cards before learning how its actual engine, mana, and interaction feel. For each of five games, record missed land drops, when Bello was first cast, qualifying permanents cast, successful combat-damage draw triggers, interaction stranded without a target, and six-plus-mana cards left in hand.

One proposed change:

Animated Army works as a first-deck model because every number connects to Bello’s text. Its 19 targets justify the theme, its 21 mana-development slots support a high curve, and its seven interaction cards prevent the engine from being the only thing the deck can do. Reuse that method, not those red-green counts, for a different commander.
