Yuan-Ti Malison

Menace makes a creature hard to block; unblockable-while-alone makes it a delivery mechanism, and that distinction is the whole design. The evasion clause is written to reward the opposite of a swarm: you want this snake sneaking in by itself, connecting for its two points of combat damage and stepping deeper into the dungeon each turn it does. Venture is the payload, and few triggers for it in blue come this clean, because the same restriction that keeps the body fragile (attacking alone, no gang, no support) is exactly the condition that guarantees the trigger fires. A 2/1 that trades in combat is unremarkable; a 2/1 that cannot be blocked when it swings solo is a metronome, advancing a dungeon room every combat step it survives. The tension built into the card is that the venture engine wants a lone attacker while every other instinct in a creature deck wants to commit a board, so it asks you to hold this one back from the alpha strike and let it do its quiet, repeatable work on the flank. It is venture at its most incremental: no evasion payment, no combat trick required, just a body cheap enough to protect and slippery enough to keep the dungeon crawl ticking over.
