Well, these are some cards I am just using because I have them. If you're battling in a lower-budget arena, just use 1 Elixir of Imortality and Jace Beleren as win cons.. Add things like Repeal, more Gigadrowse, maybe Dream Fracture and any other spells that somehow timewalk your opponent (that is: making it so your opponent can't do anything relevant on his turn and you don't lose a card).
