{U}{R}, {T}: Target creature gains flying until end of turn.

({T}: Add {B} or {R}.)
As Ruptured Flats enters, you may pay {1}. If you don't, Ruptured Flats enters tapped.

Reprising spells you control can't be countered.

Whenever a creature you control perseveres this turn, you gain 3 life. (A creature perseveres when it survives damage.)
