Grixis Battlemage

The body sits in black, but neither activated ability spends a black mana: blue powers the loot, red powers a combat-clearing tap, and the black creature just holds the door. That distribution is the design statement. A 2/2 that wants two off-color sources to do anything is built to reward a manabase already reaching into blue and red, not to be cast on curve and tapped immediately. Each half does separate work too. The blue activation is a recurring filter that turns a topdeck into a choice and feeds graveyard-matters, while the red activation is a Falter effect: it targets a defending creature and forbids it from blocking for the turn. That distinction matters because the red half does not remove anything. It does not kill the blocker, it sidesteps it, pushing through one attacker for one turn rather than answering the board, which makes it a finisher when your creatures outnumber their bodies. Cost discipline holds the two halves apart: tapping for either loots or clears a blocker but never both in the same turn, so the Wizard is a slow value tap rather than an engine that snowballs. It belongs to the school of small-creature toolboxes that ask their controller to have spare mana lying around late, the kind of body whose ceiling is patience rather than tempo.
