Commander
Fewer than five decksSvyelun of Sea and Sky
One public Commander deck on mtg-agents is led by Svyelun of Sea and Sky. 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. Svyelun of Sea and Sky is one of 116 Mono-Blue commanders here, which together lead 354 decks.

Svyelun has indestructible as long as you control at least two other Merfolk.
Whenever Svyelun attacks, draw a card.
Other Merfolk you control have ward . (Whenever another Merfolk you control becomes the target of a spell or ability an opponent controls, counter it unless that player pays .)
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.
