Stormsplitter + Sorcerer Class + Mystic Speculation

Stormsplitter
Sorcerer Class
Mystic Speculation

Requires
Stormsplitter must be on the battlefield. Sorcerer Class must be on the battlefield. Mystic Speculation must be in hand. Sorcerer Class is at least level 2. Mana needed: 5 at most, depending on how many Stormsplitters and/or other creatures you control without summoning sickness
Steps
  1. Activate any creature you control that does not have summoning sickness by tapping it, adding that can only be spent to cast an instant or sorcery spell, or to gain a Class level.
  2. Repeat step 1 until you control no untapped creatures without summoning sickness, or until you have 2 available, whichever comes first.
  3. Cast Mystic Speculation with buyback by paying 2.
  4. Each Stormsplitter you control triggers, and Sorcerer Class's third ability triggers if it is level 3.
  5. Resolve the Stormsplitter triggers, creating that many token copies of Stormsplitter.
  6. Resolve the Sorcerer Class trigger, if applicable, dealing damage to any target equal to the number of instant and/or sorcery spells you've cast this turn.
  7. Resolve Mystic Speculation, causing you to scry 3 and return Mystic Speculation to your hand.
  8. Repeat.
Results
Infinite LTB. Infinite ETB. Infinite damage. Infinite storm count. Infinite creature tokens with haste. Infinite magecraft triggers. Infinite scry 3. Infinite blue mana that can only be spent to cast instant and/or sorcery spells. Infinite red mana that can only be spent to cast instant and/or sorcery spells.
