Teferi vs Epic experiment

[lynchy]

Hello!

I frequently engage in battle with a blue/red deck that plays epic experiment.
My question is, if i flash in Teferi, Mage of Zhalfir in response to Epic Experiment, does Epic Experiment fizzle?
If not, can you elaborate how the game mechanice interact with the experiment, as I am newish and am unfamiliar with the mechanics surrounding the stack

Thankyou!

It doesn't "fizzle". Fizzling specifically refers to a spell being countered due to all its targets being illegal as it tries to resolve. Epic Experiment has no targets, thus will never fizzle.

Teferi does, however, severely limit Epic Experiment's effectiveness. When Epic Experiment resolves, it will first exile the top X cards of its controller's library. Then it will try to instruct that player to cast the appropriate spells exiled. However, since this is not a time one could normally cast a sorcery (as there is still a spell in the process of resolving), that won't be possible. Epic Experiment then instructs the player to put all cards not cast this way - ie, all of them - into their graveyard. Epic Experiment will then finish resolving and go to its owner's graveyard.

Thanks for your help, I didn't realize fizzle was a keyword.

One last thing, if I flash in Caltrops in response to attackers being declared, does it do its 1 damage to attacking creatures? Or there's possibly some priority issue?

Caltrops needs to be in play when the attackers are being declared. Once attackers are declared, you can't play Caltrops afterwards to hit them (you also can't interrupt the declaration of attackers).
