Quillmane Baku

Bounce-on-a-stick is an old idea, but the Baku family bent it into a ki-counter engine: a tribal payoff whose 3/3 body holds steady while its threat range climbs every turn you feed it. The accumulation is the entire design. Each ki counter lands when you cast a Spirit or Arcane spell, and the activated ability spends counters one-for-one against mana value, so a patient pilot watches the bounce escalate from clearing a one-drop to lifting a five- or six-drop. The catch is that firing it taps the Baku, so the bounce and the body's attack compete for the same turn: you cannot escalate someone off the board and crash in with the same activation. That tension is what keeps the engine honest. The restriction is structural rather than printed as a cost: the trigger only fires on a narrow band of spell types, so a shell that does not supply Spirits and Arcane spells leaves you holding a creature whose ability it can rarely afford to fire. That is the whole bargain. It contributes nothing on raw stats and everything on accumulation, demanding a deck built to fuel the trigger before it earns a slot, then repaying that commitment with repeatable, escalating bounce a single spell cannot match. An impatient deck gets a fraction of the value; one tuned to keep the counters flowing gets a tempo machine that widens its own reach every turn it survives.
