Overwhelming Stampede

Until end of turn, creatures you control gain trample and get +X/+X, where X is the greatest power among creatures you control.

"I trust the instincts of any beast over the advice of any human who presumes to be an expert in the art of war."

Duskmourn: House of Horror Commander

They do not fear the Ringwraiths, for those who have dwelt in the Blessed Realm live at once in both worlds, and against both the Seen and the Unseen they have great power.

You check the power of your creatures as Overwhelming Stampede resolves. For example, if you control a 2/1 creature, a 2/2 creature, a 2/4 creature, a 4/1 creature, a 5/5 creature, and a 5/6 creature at that time, each of your creatures gets +5/+5 and gains trample until end of turn.
