Halana, Kessig Ranger

Green rarely gets to point its removal at will, so this design routes around the color's limits with a mechanic it does own: creatures fighting, minus the mutual damage. Every creature that follows Halana onto the battlefield offers a taxed trigger, to fling that creature's power at something, and because it reads "another creature you control enters" rather than a combat step, it turns any go-wide or blink shell into a repeatable removal engine that never risks a blocker in return. The gating is mana rather than a once-per-turn clause: with enough acceleration, a full wave of tokens becomes a chain of pings, each sized to the entering creature. But that chain runs on the enters trigger, so its timing is inherited from whatever produced the creature. Most of the time that is a sorcery-speed cast or a token-maker resolving on your own turn, which is why the shell she anchors leans on big-bodied ETB creatures rather than the fragile utility ones green usually flings. Partner is the other lever, giving her a running mate to feed the enablers she cannot bring herself: a token-maker, a blink outlet, a source of cheap bodies to keep the trigger firing. Alone she is a 3/4 with Reach and a conditional tax, the ability inert without a stream of entering creatures. Supported, she converts green's traditional weakness (answering what an opponent has already resolved) into a sanctioned line, without a single fight spell or removal card in the deck.
