Oracle Text

Toxic 1 (Players dealt combat damage by this creature also get a poison counter.)\nOther Rats you control have toxic 1.\nWhen 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.
