Commander
Fewer than five decksKarumonix, the Rat King
Four public Commander decks on mtg-agents are led by Karumonix, the Rat King. 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. Karumonix is one of 145 Mono-Black commanders here, which together lead 500 decks.

Toxic 1 (Players dealt combat damage by this creature also get a poison counter.)
Other Rats you control have toxic 1.
When Karumonix enters, look at the top five cards of your library. You may reveal any number of Rat cards from among them and put the revealed cards into your hand. Put the rest on the bottom of your library in a random order.

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.
