Stormscape Apprentice

The Apprentice cycle gave each color a one-drop body that rented out two off-color activated abilities, paying for them through activation cost rather than casting cost. This is the blue member, and its two hats sit on the adjacent wedge of the wheel: spend white to tap a creature, spend black to make a player lose one life. Neither effect moves the board quickly, which is the design constraint that keeps a recurring tapper and a recurring life-loss engine on a 1/1 from spiraling. Both abilities share the tap symbol, so the card does exactly one job per turn, and each is gated behind mana the blue caster does not natively produce. The white mode plays defense, neutralizing an attacker or pinning a blocker before combat math settles; the black mode is a slow, repeatable life-loss clock with no lifegain attached, just one point off the opponent's total per activation. What ties it together is the casting requirement: a single blue pip on the body, with the secondary colors entered through the activations, so a blue deck can splash toward white, black, or both without bending its core. That structure rewards a manabase reaching into two extra colors, and it is exactly the multicolor deckbuilding tension the gold-heavy environment that produced it was built to encourage.
