Exodia Priest (kobolds and catacombs).

Your win-condition is to play Temporus, then on your 2 turns, play scaled nightmare and divine spirit inner fire on it. At the start of your next turn, its attack will double and you will deal 32 damage face. You would use the second turn to remove any taunts they have with dragonfire potion, shadow word death, or shadow word pain. The rest of the deck is a combination of card raw, control cards, and stalling cards. You could also include other legendary cards like Bloodmage Thalnos or other dragon-synergy cards, but I think the deck would work very well in a budget form. Overall I think the deck would be very fun to play and would be a nice change from Raza priest.
