Throw from the Saddle

Fight spells have always been green's way of turning creatures into removal, and this one splits the interaction into a strictly better shape: your creature swings for its power at a target you don't control, but takes nothing back. That one-sided damage is the whole reason the pump matters. On a normal creature the +1/+1 is temporary, a small nudge to clear one extra point of toughness. Feed it a Mount, though, and the boost sticks as a counter, so every subsequent cast climbs from a higher floor and the removal doubles as a growth engine for a body that keeps hitting the following turn. The Mount clause is the tell that this isn't a generic removal spell with a rider: it's built to reward a deck committed to the creature type, where each casting both kills something and leaves your attacker bigger for the next one. Against noncreature-heavy boards it does nothing, and it can't reach the opposing player, so it lives or dies on there being a target worth shooting. But as green removal that scales with your board rather than shrinking your hand, it asks less than a fight card and gives back more.
