Muldrotha works best with cheap permanents, especially ones that are sacrificed as part of their activation costs: Pernicious Deed becomes a repeatable board wipe, Mystic Remora is downright broken when you never need to pay for its cumulative upkeep, Caustic Caterpillar keeps blowing up stuff, and so on
A toxic and powerful rat deck designed to turn small creatures into a massive poison-based threat
This is a super sweet card
Individual characters can have different cards across the rarities, so no one Disney character is singled out as more powerful than any other
These aren't just the most obviously "broken" cards (some might not have a home yet) but they all stand out as strong contenders for future competitive decks, either in Standard or beyond
There are spell-based decks to build in this format, and this is exactly the kind of card they need to cast multiple spells throughout the course of a game
