Commander
Fewer than five decksOb Nixilis, Unshackled
One public Commander deck on mtg-agents is led by Ob Nixilis, Unshackled. 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. Ob Nixilis is one of 145 Mono-Black commanders here, which together lead 500 decks.

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.
