Commander
Fewer than five decksInquisitor Eisenhorn
One public Commander deck on mtg-agents is led by Inquisitor Eisenhorn. One deck is not enough to say what the decks that use it have in common, so this page carries the card, the deck that exist, and its colour neighbours. It fills out on its own as people build: at five decks it gains a most-played-cards list and the brewers behind them. Inquisitor Eisenhorn is one of seventy-six Dimir commanders here, which together lead 444 decks.

You may reveal the first card you draw each turn as you draw it. Whenever you reveal an instant or sorcery card this way, create Cherubael, a legendary 4/4 black Demon creature token with flying.
Whenever Inquisitor Eisenhorn deals combat damage to a player, investigate that many times. (Create a Clue token. It's an artifact with ", Sacrifice this token: Draw a card.")

A share-of-decks list needs five decks before it says anything: with one, every card it plays is in the only deck there is. This band fills in on its own as more decks arrive.
