Equipment may be important... but how much equipment are you going to use in order for two battleforges to be efective?
Bf turn 1 allos you to get 4 equipment until turn 5: chespiece, ring, cloak, and weapon. If instead of droping a second battleforge plus harmonize, you could get another two pieces of equipment (boots gloves). You still have place for three more equipment, ring, necklace, and offhand... i think having then two battlforges then is really overkill.
Maybe if you plan a really fast agression you would want 2 battleforget to get equipment pieces fast... but then, probably you will lack the mana to employ the actions...
So i would go with just 1 battleforge in order to get fast priority equipment... what mage and equipment are you thinking about?
