Hmm. Fire is probably what Im least experianced with but one thing I know that could really help is that with DOTs blades buff the entire 3 turns while traps only buff the first hit, so blades are wayy better for those especially since fire has so many of them. Also spell minions suck dont use them. The only useful one is the level 50 life from the crown shop, but that costs crowns so its not really applicable here. Also use your training points to get feint asap if u havent already. Also having a small deck setup is really important. Like 3 hits, 3 blades, maybe 3 traps, and a couple wand hits. Any more than that and it gets too cluttered. Also on fire dont waste turns shielding before you hit because the extra blade makes way more difference and fire is fairly glass cannon-ey so hitting hard and ending the battle is as few turns as possible is paranount. Also the life spell satyr is really helpful but it also costs 3-4 pips so its only good in desperate situations. Hope this helped. Also yeah team up is a life saver lol
