Thinking of this FM build, I can't see how you got double battle fury on yourself. Or BF plus charge. This is going to look really silly but how is this possible? I thought FM was all about Galvitar double strike plus Dancing Scimitar?
Typing this on a train so can't reference the cards to work out how you did this!
Thoughtspores can have Battle Fury or Charge bound to them so that you dont have to cast them on one of your own actions.
A Thoughtspore can cast Battle Fury, then you Quickcast Charge.
Then you move forward and attack twice-
Charging Quick Attack 1, Battle Fury Quick Attack 2. (and attack 3 from Dancing Scimitar if you have it on)
If you dont have to move, Battlefury yourself and use the full attack option for
-Doublestrike 1, Doublestrike 2, Quickattack 1. (and attack 4 from Dancing Scimitar if you have it on)
Generally though, against an Iron Golem, youll want to Battle Fury and use your Quickattack twice instead of the double stroke.. because the quick has a natural 2 pierce while the Doublestrike/Sweep option has 0 Pierce.
