This looks like a very dangerous deck, yet looking at some of the cards it seems a bit "clunky' to me. Do you have any ways of ramping into your mana base or recurring your spells that do the wheel abilities? Also one thing you could try doing is adding
K'rrik, Son of Yawgmoth to your deck. This will naturally reduce the mana you spend across the deck and will help you
execute your plays a lot faster. What do you think on this?
