Wasteland Scorpion

Deathtouch on a 2/2 means the body is never embarrassing on defense: it trades up against anything that walks into it, so even a dragon dies to the block. That is the floor. The ceiling is that this card is never a dead draw, because the same piece can be spent for a fresh card when the board has stalled or when you have flooded on lands and want action instead of another blocker. What makes the design durable is that it asks nothing at cast time; there is no mode to lock in when the spell goes on the stack. The decision is entirely about timing: commit it as a roadblock, or discard it for a card when the game wants gas. Deathtouch is the keyword that keeps a small creature relevant no matter how large the biggest threats on the table grow, and welding a discard-to-draw outlet to it strips out the only real liability such a creature carried, the risk of drawing a body you no longer need. This is the black filler creature refined to its most flexible form: rarely a card you would ship back in a mulligan, because it fills two roles a grinding deck always has use for. The lesson generalizes past this printing: give a modest body deathtouch and a cheap cycling clause and you have a card that is hard to make truly bad.
