Whenever you waterbend, earthbend, firebend, or airbend, draw a card. Then if you've done all four this turn, transform Avatar Aang.
Flying
Spells you cast cost less to cast. (This can reduce generic costs.)
At the beginning of each upkeep, you may transform Aang, Master of Elements. If you do, you gain 4 life, draw four cards, put four +1/+1 counters on him, and he deals 4 damage to each opponent.
Aang is a five-color value engine: assemble cards with the four bending keywords (water, earth, fire, air) and trigger draws every time you bend, while looking to perform all four in one turn to flip into Aang, Master of Elements. Once flipped, your spells effectively cost WUBRG less, and each upkeep you can flip back for 4 life, four cards, four counters, and 4 damage to each opponent, snowballing card advantage into a lethal burn/beatdown finish.
Relentless card advantage—every bend draws a card, and the flip nets four more plus repeatable upkeep draws.
Built-in evasion (flying) and a recurring three-player burn clock that can win without combat.
Massive cost reduction on the back side lets you chain expensive bombs and rebuild fast.
Full five-color identity opens the best removal, ramp, and tutors in the format.
Needs a critical mass of bending sources to reliably hit all four types in a turn.
Five-color mana base is greedy and prone to stumbling without strong fixing.
High-value commander that draws removal; losing Aang stalls the engine.
Front side is a fragile 3-power flyer with no protection of its own.
Protects your flipped Aang and life total during the turns the burn engine is racing opponents.
Prioritize flawless mana—dual lands, fetches, and ramp like Chromatic Lantern and mana rocks so you always have all five colors for bending and flipping. Add a dense package of bending-keyword permanents to guarantee hitting all four types each turn, plus protection (Heroic Intervention, Lightning Greaves) to keep Aang alive. Top end should be efficient finishers and tutors (Demonic Tutor, Eladamri's Call) to find your engine pieces, leaning into the cost reduction with high-impact spells.
