A fun first draft of this concept. Dragonlord-Ignis Rex is one of the most reliable sources of self-discard we have so far. This allows us to discard our big knights and then play Vengeful Heir for value. An inconsistent combo, but might provide fire a bit of oomph to compete with all the other big minions floating around.

It's actually quite difficult making a low-to-the-ground mono-Fire deck, so definitely massive room to improve the list. Ignis allows us to play more minions as every fire card can be turned into a removal spell.
