Purple-Crystal Crab

The blue baseline for a chump that pays you back. A 1/1 for two mana that draws a card when it dies is doing the same structural work that black's death-cantrip creatures have long specialized in, only in the color least likely to be trading in combat. The body exists to be spent: block once, feed to whatever wants a creature in the yard, and the card you draw makes the exchange even. What keeps this humble rather than abusable is that the trigger fires on death only, not on any zone change, so blinking it or bouncing it back to hand nets nothing; you have to actually let it die to collect. That single condition is the whole restraint on an otherwise frictionless cantrip attached to a warm body. It is a small, honest piece of design: a creature that turns the inevitability of a 1/1 losing a fight into card advantage, printed for players who want their early plays to keep contributing after they leave the battlefield.
