Looks like your basic mono-fire. Pretty good. Fire's only weakness is a lack of healing... and that's what SoG is for.
Now, do as you do in Tower defense;
Specialization!So, now. You can either
rush (http://elementscommunity.org/forum/index.php/topic,11593.0.html) or
stall (http://elementscommunity.org/forum/index.php/topic,6515.0.html). I like stalls more than any rush, so that's what I'm going to put.
-4 dragons (who needs creatures?)
+3 fire storm (CC.)
+5 SoG (Fire+Healing=Win, plus, this gives you lots more EMs)
+3 Fire Buckler (In any good firestall, the buckler is very important)
+3 rage pot (More CC.)
(Disclaimer- Changes may not work as intended. Especially with unupped versions of cards, if you don't have them.)
Edit:Put in links to actual examples put by experienced members of the community.
