Rampage is a creature only ability that was first seen in the set Legends and was last printed in Fifth Edition, until the creature Craw Giant was released in Timespiral. Rampage grants the creature the ability to power up from each blocker. However, due to most rampagers not having trample, Rampage wasn't seen as a good ability because most people would not block a creature with two or more creatures unless it had trample. However, there are updated version of the ability rampage that trigger separately.
