Mulligans
General Mulligans
General game plan is to just be handlock. Get some early interaction and try to make sure you keep your hand big for the important cards. I wouldn't mulligan for Lorekeeper usually.

Stay alive while you resolve a huge threat. Huge threats are pretty easy to find but these two are the best (I think). Just try to find the interaction in the muligan and you will draw into the threats.
I really like this idea, definitely going to try to make it work after the expansion drops 😀 Giants.
