Mulligans
General Mulligans
Beckoner of Evil and Plated Beetle are both pretty decently statted 2 drops to pop out on an early board, and playing Shadow Ascendant right after one of the two can generally give you a pretty favorable lead in the early game.
Aggro Mulligans
Against aggro you generally wanna hold off the board until you can gather more control around mid-game, and Doomsayer and Scalehide are pretty good and maintaining some early board control.
Control Mulligans
Against a control deck I usually feel safe enough to keep at least one of these 6 mana cards, as both can be pretty devastating once played. I generally prefer to keep Lady in White, however sometimes if I think my opponent is running a 1 mana spell dependent/heavy deck I'll go for the Geist instead.
This deck is a meme, but it’s pretty fun and I’ve actually won the majority of my games with it so I thought I’d share!
