Archeon the Enduring

Trample, duel (Once per turn, you may start a duel
with target creature you don't control. Then,
this creature and the chosen creature are in a duel. Creatures in a duel can't be targeted by spells and abilities other than their own abilities and fight
each other each combat step. A duel ends when one
of the participating creatures leaves the
battlefield.)

Archeon may duel up to two additional times each
turn.
