Foe-Razer Regent

Most fight cards stop at the trade: your creature swings at theirs, somebody dies, the spell is spent. This Dragon reframes fight as a recurring growth engine. The enter-the-battlefield fight is the obvious half, spot removal stapled to a 4/5 flier that can clear a blocker the moment it lands. The standing trigger is where the design opens up: any creature you control that fights, not just this Dragon, banks two +1/+1 counters at the beginning of the next end step. That delay is doing real work. Fight is not combat, so the buff arrives on its own trigger later in the turn, and any creature that lives through an exchange grows permanently. The engine rewards a deck stocked with repeatable fight effects rather than a single one-shot. Green has always treated fight as its answer to spot removal, trading body for body because it lacks clean destroy effects; this turns that compromise into an accumulating advantage, since every exchange your creature survives makes it bigger for the next one. The 4/5 frame is built to win those fights itself: enough toughness to eat most blockers, enough power that the counters push it into hard-to-block territory in the air. The job is clean, a green fatty that converts the color's removal-by-combat into a snowballing board, with the wrinkle that the delayed counter trigger fires regardless of whose fight prompted it.
