Yes, you can create this loop, if you have casted some instant or sorcery before Twincast, but this won't work with Gelectrode and Thermo-Alchemist. Copies isn't cast, copies just placed into stack, so the triggers of aforementioned cards won't activate.
So it would only ever be two casted spells in this situation?
Example of the turn:
Main phase:
There is a Thermo-Alchemist without summoning sickness on the field. I cast Twincast then cast Reverberate at instant speed targeting Twincast, then use that copy to target the Reverberate etc....etc... this would not create a infinite loop?
I think I get what your saying, I can theoretically have an infinite loop of the copies of the two, but only ever be casting two cards, correct? I just wanted to be sure.
If people are sick of reading about stuff just stop taking part. You have 100% control over what you read. Simic Ascendancy isn't going to get banned just because you didn't tell someone to shut up on the internet.
When reverberate resolves it copies twincast and goes to the graveyard. The twicast copy it created no longer has a target and is countered by the game rules.
You can change the target of the copy-Twincast to the original Twincast as per the instructions of Reverberate. This copy then creates a copy of Twincast, which again can be made to target the original and so forth.
Remember, that being countered by the game rules occurs, when the spell with no more legal targets would resolve, not right away.
The point of this would be is to infinite burn with Gelectrode, or Thermo-Alchemist.
Thank you.
P.S. I understand that copy spells cant target themselves. This isn't that type of question.
EDIT: grammar.
You aren't casting infinitely many spells because copying a spell doesn't cast it, it just creates one on the Stack.
