Riptide Crab
A 1/3 with vigilance and a draw-on-death clause is white-blue patience compressed into one body: it never wants to win combat, only to outlast it. The toughness lets it stand in front of two-power attackers indefinitely, the kind of early creature it neutralizes without dying; the vigilance means it can chip in for one while still holding that ground, refusing to be the wall that only ever sits back. The death-trigger is what removes the usual cost of a defensive blocker. Most early speed bumps lose you a card the moment they finally trade or chump; this one converts its own death into a replacement, so the body and the card it leaves behind are never the same expenditure. That changes how an opponent reads it. Spending removal funds a draw step, which makes the Crab a poor target. Forcing it to chump a larger attacker costs the opponent no card, but still hands its controller one, so even being run over has a price the aggressor would rather not pay turn after turn. The math is quiet and asymmetric: the Crab is happy to lose any individual exchange because losing is when it draws. Inconvenient to kill and unrewarding to walk past, it trades time for cards in the way the color pair has always preferred to fight.
