Choose one —
• Fight the Current — Return target nonland permanent to its owner’s hand.
• Find a Crossing — Target creature gets +1/+0 until end of turn and can’t be blocked this turn.
Casting this spell and choosing the Find a Crossing mode targeting an attacking creature that has already been blocked won't change or undo that block. It will still get the +1/+0 though.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
