Rimrock Knight // Boulder Rush

Two attacking functions parked in one card, and neither wants to play defense. Boulder Rush is a shrunken Giant Growth: +2/+0 for a single red mana rather than green's +3/+3, cheap enough to steal a combat step or push through the last point of lethal. This is what the Adventure mechanic buys: casting the instant exiles the card rather than sending it to the graveyard, leaving the creature waiting to be summoned later at its full . What eventually lands is a 3/1 that can't block, pure forward pressure, a body whose inability to hold ground means the deck around it must already be the one attacking. Where Adventure usually sells flexibility (a removal spell now, a blocker later; a bit of value now, a threat later), this card refuses the hedge entirely. Both modes push the same plan: the instant wins a race, the creature keeps one going, and nowhere along the way does the card offer a defensive fallback. That single-mindedness is exactly what a low-curve red deck wants from a two-mode card, which cares less about optionality than about never drawing a blank. The sequencing is the pilot's problem to solve: fire the pump early to close a game, or hold the card as a creature when the board wants a fresh threat. Every branch it offers still points the same direction.
