imho this is too slow compared to rainbow pillarless fast decks...
my frequent 1st turn with my deck is :
ball lightning, cremation, nova, (2) 7/1 Lava destroyer in play.
if you are lucky you can drop you whole hand on the table (werewolf, giant frog, arsenic.. )
I know this is the mono deck fire section, but why should i choose this kind of deck against a rainbow fast?
