Rakish Scoundrel

Deathtouch on a 3/3 already means this body trades up against anything it fights, but the enters-or-turned-face-up trigger is what turns a fair midrange creature into a two-part trap: it grants indestructible to any creature, so the flip point doubles as a combat trick. Play it hidden for three, let an opponent aim removal or a losing attack into your board, then unmask it at instant speed to save the target and land a deathtouch blocker in the same beat. The trigger also fires when it enters straight from hand, so the honest line still buys a one-turn indestructible for something you care about; the face-down mode just layers a second window and a bluff on top. That structure is why the card prefers to enter hidden: an opponent looking at a small warded body cannot tell whether it is empty morph fodder or a protection spell loaded behind an elf, and the ward makes prodding it costly. It is a piece of interaction dressed up as a creature (the pun runs straight through the mechanic), built to punish anyone who commits to a line before the concealed card resolves.
