If you have one I would add a mirror force, they come in handy.
+1 Mirror Force
not sure what to take out though...

please r/f my Fire/Burn Deck

believe me, if i had extras to toss around i would

+treeborn frog
+3 ufo turtle
+2 creature swaps

-2 spear cretins
-infernal dragon
-question
-cost down
-twister

I would change up the dragon selection felgrand, darkblaze and tyrant are really bad cards personally i would work around and try to sqeeze in a third ladd
