Trample, haste : Rampaging Raptor gets +2/+0 until end of turn.
Whenever Rampaging Raptor deals combat damage to an opponent, it deals that much damage to target planeswalker that player controls or battle that player protects.
Unlike many similar abilities, Rampaging Raptor's triggered ability triggers whenever it deals combat damage to an opponent, not to a player. If it happens to deal combat damage to you (usually due to a redirection effect, which would be unusual), the ability won't trigger.
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.
