Mulligans
General Mulligans
Firefly & Mana Wyrm general good earlygame
Keep Kirin to if you have a secret and think you can handle the pressure
Tar creeper vs aggro and possibly volcanic potion
A theory raft before the expansion comes out trying to use mages many good odd cards. Not a pro player but relatively high ranking and played since GvG. Feedback appreciated!
The Firelands Portal is part of the Karazan, so you can’t use in the future in standard decks.
