Commander
Fewer than five decksTyvar the Bellicose
Four public Commander decks on mtg-agents are led by Tyvar the Bellicose. Four decks are not enough to say what the decks that use it have in common, so this page carries the card, the decks 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. Tyvar the Bellicose is one of eighty-two Golgari commanders here, which together lead 711 decks.

Whenever one or more Elves you control attack, they gain deathtouch until end of turn.
Each creature you control has "Whenever a mana ability of this creature resolves, put a number of +1/+1 counters on it equal to the amount of mana this creature produced. This ability triggers only once each turn."

A share-of-decks list needs five decks before it says anything: with four, every share is a multiple of 25%. This band fills in on its own as more decks arrive.
