My final "Rainbow" Dragon Magic the Gathering Deck!?

This deck has too many colors and not enough mana accel. There's a card that would go well with this deck that's called Sneak Attack. It lets you put a creature from your hand into play and it gains haste but you have to sacrifice it at end of turn. So you can slap down a bunch of dragons and swing in and then get them into the graveyard for Scion of the Ur-Dragon's effect. Dragonstorm would be ineffectual in a deck like this because you don't have many non-dragon spells. In a dedicated Dragonstorm deck there are only 6 dragons: 4 Bogarden Hellkite and 2 Hunted Dragon(they're in in case you draw a Hellkite) and the rest of the deck is setup to get a decent Storm count.
