Infinite
Mister Fantastic, Dynaheir, and Seeker of Skybreak trigger-copy loop
Infinite copies of a controlled triggered ability. This is not a win by itself without an appropriate trigger or payoff.
Required Cards
Setup
- Mister Fantastic, Dynaheir, and Seeker of Skybreak are on the battlefield.
- Mister Fantastic can tap and you can pay {R}{G}{W}{U}.
- Seeker of Skybreak can tap and can legally target Mister Fantastic.
- The Dynaheir prerequisite for copying the relevant activated ability is satisfied.
- You control a triggered ability on the stack that is legal for Mister Fantastic to target.
- A separate trigger or payoff exists if the line is expected to win.
At least {R}{G}{W}{U} for Mister Fantastic plus any mana required by the Dynaheir/untap setup.
Sequence
- Put a controlled triggered ability on the stack.
- Activate Mister Fantastic targeting that trigger.
- Use the Dynaheir-supported copy setup and Seeker of Skybreak untap sequence to reuse Mister Fantastic.
- Repeat while the prerequisites remain true.
- Resolve the copied triggers or convert them through a payoff.
Interruption Points
- Remove or tap Mister Fantastic before activation.
- Remove Dynaheir or Seeker of Skybreak.
- Counter or remove the target triggered ability before Mister Fantastic's ability resolves.
- Stop activated abilities with Cursed Totem-style effects.
- Deny WURG mana or remove the payoff trigger.
Mister Fantastic role: Mister Fantastic is the targeted triggered-ability copy engine.
Timing: Mister Fantastic and Seeker of Skybreak must be able to tap.
Rules notes: Mister Fantastic copies only triggered abilities you control. The loop creates trigger copies, not a win condition by itself. The exact Spellbook prerequisites and mana state must be checked before publication-level combo claims. Mister Fantastic rule 1: Mister Fantastic's color identity is WURG because his activated ability contains red, green, white, and blue mana symbols. Mister Fantastic rule 2: His combat draw trigger checks whether you cast a noncreature spell earlier that turn before the beginning-of-combat trigger event. Mister Fantastic rule 3: Copying the combat draw trigger twice can draw two additional cards, but only after the original trigger exists. Mister Fantastic rule 4: The activated ability targets a triggered ability you control, not an activated ability, spell, or opponent's trigger. Mister Fantastic rule 5: The copied triggered abilities are created on the stack and can choose new targets if the copied trigger has targets. Mister Fantastic rule 6: Mister Fantastic must be untapped and able to tap; summoning sickness stops the tap cost unless haste or another permission effect applies. Mister Fantastic rule 7: Removing Mister Fantastic after his activated ability is activated does not remove that ability from the stack. Mister Fantastic rule 8: Countering or removing the targeted triggered ability before Mister Fantastic's ability resolves can stop the copies if the target is illegal. Mister Fantastic rule 9: Untapping Mister Fantastic after activation can let the deck copy another triggered ability if it can pay WURG again. Mister Fantastic rule 10: Dynaheir-style prerequisites matter because the copied ability must fit that card's timing and mana-value conditions. Mister Fantastic rule 11: A loop that makes infinite trigger copies still needs an actual controlled triggered ability or payoff to win the game. Mister Fantastic rule 12: Mister Fantastic, Reed Richards is a separate card with different mana cost, set, and Oracle text.
