[Reiterate/Lightning Bolt combo]
- with 4 exp counters (and Mizzix out), cast a a rit (eg., Desperate Ritual, Pyretic Ritual, Seething Song... something that nets you 1 more mana than it costs to cast)
- copy the rit with Reiterate, paying the Buyback cost... then recast the rit and go infinite mana
- now you can cast Lightning Bolt for a million times (no Mizzix discount), but Reiterate the LB with all of your infinite mana
