Twilight Panther

A mono-white one-drop whose payoff is gated behind a black mana symbol: the printed 1/2 body defends a corner of the board on its own, but the design points squarely at the switch, which only comes online when the manabase can produce black. Pay the black and the body gains deathtouch, so it trades up against anything it blocks or gets blocked by. This is not free: with no first strike and no way to survive the exchange, it dies alongside whatever it kills against any attacker with two or more power. What the black buys is not a repeatable roadblock but a one-for-one price shift, letting a small body threaten to drag down a large one and making an attacker think twice about running into it. The activation is a switch, not a sink; granting deathtouch a second time in a turn does nothing, so surplus black mana finds no purchase. This is a white creature built for a deck that reliably fields black mana too: it only matters on both sides of combat once the second color is online, rewarding a committed two-color build rather than a splash. On an empty board it is a modest early play; with black available it turns each combat step into a real question about whether the opponent wants to lose their best creature to trade with a one-drop.
