Commander

Five decks or more

Loki, the Deceiver

Eleven public Commander decks on mtg-agents are led by Loki, the Deceiver, and eleven different people built them. What sets them apart: six of the eleven run Doctor Doom, King of Latveria, and six run Mysterio, Master of Illusion. Loki is one of fifty Grixis commanders here, which together lead 767 decks.

Whenever Loki attacks, create a tapped and attacking token that's a copy of another target Villain you control, except it isn't legendary and it's an Illusion in addition to its other types. Sacrifice that token at the beginning of the next end step.

Whenever one or more Villains you control deal combat damage to a player, draw a card.
