Rapier Wit

Cantripping tappers are old white technology, but the stun counter is what pulls this one out of the "cheap Peel from Reality substitute" bin and into genuine tempo territory. Tapping a creature and drawing a card is a fair trade that never quite justified a slot; the difference here is the asymmetry between casting it on your turn versus the opponent's. On your own turn it functions as soft removal, since the stun counter eats the creature's next untap step and effectively blanks it for a full rotation. On the opponent's turn it reverts to a plain tapper: fog a would-be attacker, break up a crew, hold up a card off an end step, no counter attached. That split is the entire design, and it rewards proactive play in a way tempo instants rarely do, since the payoff for casting it on the offensive is a strictly better mode. The stun counter's own text (a permanent that would untap loses the counter instead) means it is genuinely a one-turn tax rather than permanent lockdown, which keeps the effect honest at instant speed and two mana. The real trick is that it converts white's traditionally reactive tapping into a tempo lever, letting an aggressive deck disable a blocker, connect, and replace the card in one motion.
