The Wondrous Wasp

Tap-down and ability-suppression have historically lived on separate cards, and stapling them together on one flash body is what makes this worth studying. The enters trigger does two things at once: the tap buys an immediate tempo turn, but the payload is the ongoing suppression, which strips a single problem creature of everything that made it dangerous for as long as this stays alive. That conditional matters more than it looks. The lock is durable only as long as a 2/1 flier survives an open board; kill it and the abilities snap back on, so what you have bought is contingent rather than permanent. Where blue usually neutralizes a keyword-dense threat by bouncing or countering it, this leaves the creature on the battlefield and just switches it off, which is a genuinely different axis of interaction. The timing has an important limit, though: suppression only reaches abilities going forward. Holding up flash lets you flash it in during combat or in response to a trigger, but if a creature has already activated an ability, that ability is on the stack and resolves regardless; losing its abilities afterward does nothing to stop it. So the sting is at its best pre-empting a threat rather than answering one mid-resolution: neutralize the attacker before it swings, mute the value engine before it fires, and leave an evasive body behind to do the rest.
