Went back to this after getting sick of playing mono shadow. I've just gone on a 5-0 streak from Diamond 2-1
This deck is very straight forward. Don't forget you can
Dragon Forge to play a weapon on
Akko, Inspired Artist on turn 3.
With
Touch of Force and
Rampage you can get some pretty insane combos on your weapons and units. It's bad ass
This is basically Why I Salty's stonescar Akko Mastery list but since expedition doesn't allow some of the cards I've just reworked it with Justice and it packs a punch.
Keep an eye out for new 1 or 2 cost weapons that could fare better in coming updates. All the Fire units have great mastery skills and shouldn't be replaced.
Varret, Hero-in-Training is also Really good
