Commander
Fewer than five decksCosima, God of the Voyage
One public Commander deck on mtg-agents is led by Cosima, God of the Voyage. 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. Cosima is one of 110 Mono-Blue commanders here, which together lead 323 decks.

At the beginning of your upkeep, you may exile Cosima. If you do, it gains "Whenever a land you control enters, if Cosima is exiled, you may put a voyage counter on it. If you don't, return Cosima to the battlefield with X +1/+1 counters on it and draw X cards, where X is the number of voyage counters on it."
The Omenkeel
Whenever a Vehicle you control deals combat damage to a player, that player exiles that many cards from the top of their library. You may play lands from among those cards for as long as they remain exiled.

No most-played cards yet
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.
