fahrenheit is a main dmg dealer, and you dont want it to get destroyed or stolen, i even would suggest 4, OR not a single one+less towers+ rage pots/deflags instead of firebolts.
but i would replase 2 dragons with towers or 1 tower/1 phoenix.
i have to say, atm im testing some similar types of this deck, and i havent found a REAL good way till now, all are nice and can be fine, but i still have problems.
