Refuse to Yield
The +7 toughness is the tell. A trick that pours its bonus into survival rather than reach reads as unglamorous because it does not close games, but it rewrites a combat step more reliably than a raw power boost would: seven extra toughness answers most burn and most combat damage, where the reverse split would only threaten a kill. The untap rider converts a rescue into an ambush. A tapped attacker is normally spent on the crackback, off the board for the swing back; refresh it and it can stand as a blocker, eating an incoming threat while shrugging off whatever the opponent priced for the smaller body. That is the whole trap: attack into an open board, run into a blocker that just gained seven toughness and cannot profitably be pushed through, and watch a removal spell meant to clear the way come up short. The lopsided +2/+7 distribution builds a wall out of a middling body for a turn, and the untap recovers a piece the combat math had already spent. This sits in the older white tradition of stalling until the numbers tip and standing back up in a stronger position, rather than the red-and-green instinct to race. It poses a pointed question to the attacker: is the swing worth walking into a creature you had counted as tapped, one that now survives everything you had planned for it?
