Ty Lee, Chi Blocker
Tapping a creature and holding it down is old technology: Icy Manipulator did it for a colorless price, Frost Titan did it on a body. What this design does differently is fold the effect into a flash creature that also scales with your spellcasting, which changes what the enters trigger is actually for. The lockdown lasts only as long as you control the permanent, so the effect functions as an ongoing tax rather than a fire-and-forget answer; it reads more like Opposition than Pacifism. Flash is doing quiet structural work here. It lets the tap resolve on the opponent's turn, freezing an attacker before combat or an untapped blocker before your own alpha strike, and it means the enters trigger can be held until it does the most damage. Prowess on a 2/1 turns a stalled, tapped-down board into an opening: every noncreature spell you cast to protect the lock also pushes the body toward relevant damage. The whole package leans on tempo rather than removal, which is a coherent identity for a small blue creature. You are not killing the threat, you are removing it from the game state for as long as you can keep the parasite alive, and every burn or bounce spell your opponent spends breaking the lock is a spell not advancing their own plan.
