Anton

Anton was a green and white planeswalker first mentioned in the Duelist #1. He dueled Karshan on at least three occasions.

Duel for Dominia
In an epic series of three duels, Anton battled Karshan for dominion over the Multiverse. Anton preferred dying over watching Karshan rule over the Multiverse.

In their final battle, Anton's cottage on the Great Plains was destroyed by stone rain. He summoned a colossal spider and the Scryb sprites from the surrounding forests. His summoned creatures were all destroyed quickly and he fell to Karshan's goblin raiding band and juggernaut.

His dying oath was that his spirit would reclaim what was his after others had battled Karshan.
