Malamet Battle Glyph

The green fight spell has always paid for its efficiency with a coin flip: point your creature at theirs, and if the math is wrong you lose your creature alongside it. The counter clause here rewrites that math, but only under a narrow condition. If the creature you control entered this turn, it grows before the fight resolves, which can turn a summoning-sick body fresh from your hand into a removal spell that survives what it kills. That "entered this turn" restriction is the whole trade: the buff isn't free, it's a payment for a threat you just committed. Cast this on a creature that has been in play since last turn and you get a plain fight, priced at a single mana. Cast it the same turn your attacker lands and the pump times perfectly, both creatures sized more favorably when they trade blows, so the exchange tilts in your favor: with the numbers right their creature dies, yours lives, and you have spent one card to do it. The design encourages a specific sequencing rhythm: hold the spell until you have new pressure on the board rather than firing it on an established threat. It rewards the deck that floods creatures every turn over the one that plays a single fat body and sits behind it, a subtle nudge toward staying proactive and turning each new arrival into a removal window rather than trading into a stalled board.
