Ty Lee, Artful Acrobat

The chi-blocker rendered as a tempo threat built around a two-part turn. Prowess and the pay-to-strip-a-blocker ability sit at opposite ends of the sequence rather than firing together: prowess wants a noncreature spell cast during your main phase, growing the 3/2 into a 4/3, while the attack trigger asks for held open into the declare-attackers step. The card's job is to make those two windows serve one plan. First the spell pumps the body; then, when it swings, the extra mana buys a clear lane so the enlarged attacker connects. The blocker-removal is priced low ( per attack) but deliberately narrow: it locks down a single creature, not the whole wall, so this is an enabler for a wider board rather than a lone finisher. That single-target clause is the restriction that keeps it fair, forcing a choice about which blocker to peel off each combat. Spell density is what ties the halves together: a deck packing cheap noncreature spells gets both payoffs, spending those spells to trigger prowess in the main phase and reserving mana to punch a hole in the defense on the swing. It rewards a build where the spellchain and the attack step are planned as one motion, converting a shell of cheap interaction into consistent, hard-to-block damage.
