Fire Squad

Basically just threw any Merc with Fire into this comp, but here are some ways I expect it to be good.

Heating Up with Baron has no cooldown, you can spam it every turn to make sure your Fire abilities proc as soon as possible. Very curious to see if it stacks, like if we press Heating Up every turn, does it just get lower and lower every turn? If yes, that is bonkers good. Other than that, I like Living Bomb with Burning Bracers because we also run Apocalypse with Diablo allowing us to Crit all enemies, basically dealing 48 damage to an entire board not including any additional buffs.

Antonidas may be one of the weaker Mercs, but I like Fireball Storm with Searing Pendant as a potential closer with Apocalypse as well.

Already hit on Diablo a bit, but running Claws of Terror to help with reducing speed of enemies further and allowing us to disrupt certain enemy moves. Apocalypse is the main reason we run Diablo though as it's a Fire ability and just super strong overall.

Voone is mainly in there to get us a second fighter, but does have a Fire ability in case we need it for a Fire Combo play, but the main idea is to have a huge Evasive Wyrm which will do 50 damage as long as we have Wyrm Claws equipped...that seems nasty.

Alex is in for her wealth of Fire abilities. It's possible we want to be running a different piece of equipment than the Brooch. The utility of Dragon Breath seems strong not to mention Dragonqueen's Gambit being highly effective against a super buffed fighter like Samuro or Sylvanas.

Finally we Ragnaraos, again just a host of Fire abilities. Blazing Rune essentially gives all our abilities +3 damage, some of which are repeatable and often times we are dealing Crit damage to all enemies so this just scales even better. Could be some major pop off turns with DIE Insects cleaning up a board hit by Apocalypse and Living Bomb.  (Living Bomb 5, Apoc 6, DIE 10) - all of which are likely one speed faster from a previous use of Heating up.

Not sure how strong this will be, but it seems fun.
