Basking Broodscale

The trigger reads like a one-time upgrade and behaves like an engine. Adapt only puts a counter on a creature with no +1/+1 counters, so a naked Broodscale can adapt exactly once. But the payoff triggers on counters entering, not on adapting, and the Eldrazi Spawn it makes is a colorless mana source you can sacrifice for . Feed that mana back into the adapt cost, add a way to remove the counter you just placed, and the loop reopens: the creature has no counters again, so adapt is legal again, so you make another Spawn, and the whole thing spins as fast as your counter-removal and remaining green mana allow. That is the design tension the card is built around. On its own it is a 2/2 that grows once and leaves a token behind, a fair rate for two mana. Attach an engine that repeatedly places +1/+1 counters on it (strip the counter, then place a fresh one) and the trigger becomes a repeatable mana-and-body factory rather than a single pump. Devoid is the quiet enabler underneath it all: the Spawn and the Broodscale are colorless, which matters for anything keying off Eldrazi or colorless permanents. It is a combo piece wearing the costume of a modest colorless two-drop, and the gap between those two readings is exactly what the trigger's dependence on repeated counter placement is guarding.
