Hecarim, The Shadow of War

Trample, Haste
Devastating Charge-Whenever Hecarim attacks, each other attacking creature you control gains trample and gets +X/+0 until end of turn, where X is Hecarim's power.
Spectral Stampede-Whenever a creature an opponent controls dies, you may pay {1}{B}{G}. If you do, create a 3/3 black and green Spirit Horse creature token with trample.
“The living tremble at the sound of my hooves.”
