The Whiteboarder

White-bordered creatures you control get +1/+1.

Whenever you cast a creature spell, note its power, toughness, or one of its abilities. (Perhaps write on something you can reuse infinitely.)

{6}, {T}: Create a white-bordered blue Elemental creature token. It has noted power and toughness and up to two noted abilities. Erase whatever text you use this way.
