Can you help with MTG Red/Blue Deck?

Try to increase the amount of multiples that you have. If you get an Ophidian Eye you can combo it with Niv-Mizzet for damage equal to the cards left in your library (Niv-Mizzet: Tap, draw a card. Whenever you draw a card have "" deal damage to target creature or player. Ophidian Eye: Whenever enchanted creature deals damage to a player draw a car. GG). I'd probably include more card draw seeing as you have Niv-Mizzet and I'd try to get a hold of the card with Wizardcycling (costs 3 to wizardcycle to find any wizard in the deck).
