Dragons

my refined dragon deck. made it a ramp deck to make it faster to cast high mana costing dragons. placed some combo cards in the deck to: souls fire, zektar shrine expedition, bogardan hellkite. goal is to dish out high damage to the opponent in game end since the deck is slow in the start and would definitely need to catch up on the initial damages done by the opponent. the trick is to soul fire on the elemental created by the zektar shrine (automatic 7 damage + possible additional damage of up to 7), and bogardan hellkite (5 damage when hellkite plays + 5 damage by souls fire + possible additional frm hellkites attack). quite afraid of fast decks though like goblins, and creature removal like terminate, burst lightning, or doom blade since i have only 7 dragons all. i was thinking of adding more dragons or removing the zektar shrine. may i get your comments on how to make this work better. thanks.
