Quilled Charger

Tap two power worth of your other attackers before combat, at sorcery speed, and this 4/3 turns into the threat that actually gets through: +1/+2 makes it a 5/5, and menace forces two blockers into a body that already trades up. The cost is paid in board width. The creatures you spend saddling are the ones sitting out of the swing, so you are collapsing several attackers into one hard-to-block threat, and you are committing to that conversion before the block is declared. There is no combat-step wiggle room; the whole thing is locked in at sorcery speed, which means you commit to how the trick pays off without knowing how your opponent will answer it. That front-loading is the honest read on most Mount payoffs: they are aggro-slanted cards that want a battlefield already in place, not comeback tools. From behind, with nothing to tap, this plays like a vanilla 4/3 that does none of the work its text promises; ahead, it converts a wide board into a swing that is expensive to stop. Within the Mount lineage it sits in the plain-but-functional tier, a red beater whose entire identity is that it hits harder once you have spent the turn setting it up.
