Spider-Woman, Stunning Savior
The static tax hides inside a two-drop flier. Most tempo effects that punish an opponent's development do it once and cost a card: a bounce spell, a tapper you have to activate, a Frost Titan attached to a bigger body. Venom Blast folds the effect into a permanent's continuous presence, so every artifact and creature your opponents play arrives tapped for as long as this stays on the battlefield. That is a soft Kismet stapled to a 2/2 with evasion, and the combination changes what the two ability lines are worth to each other: the flier applies pressure while the tax denies your opponents the untapped blockers and mana rocks they would use to stabilize, and the tax matters more the longer the flier survives to keep the clock running. The design lives in the gap between hard denial and pure aggression. It does not counter anything or remove a threat; it just slows the whole opposing board by a beat, a compounding pressure that decides races rather than grinds. The flexible casting cost keeps it honest, letting either white or blue foot the bill while ensuring the card slots into the tempo-oriented shell it was built for rather than any deck that simply wants a cheap body.
