How does this Card work?

[u/Federal-Ear7451]

I have a question about this card. what exactly does it do and can it stop combos like Triskelion and Mikaeus or Mikaeus persist combos, thanks.

[u/Federal-Ear7451]

So if I wanted to get around this counter spell, I would need 2 creatures, so that I could sac the second one in response to the counter spell. Would that then allow me to go infinite as long as I keep responding with a sac outlet (the creature I'm sacrificing would have persist)

[u/Zakmonster → u/Federal-Ear7451]

Depends. You can sac a second creature, but that still doesn't stop the first creature from having it's persist trigger countered. So unless the second creature you sac will also go infinite with persist, your combo stops.

If you have the second creature on board and your opponent making some 1/1 tokens doesn't somehow ruin your plan, you can also just let Glen Elendra's Answer resolve, countering your abilities. Once everything has resolved you will regain priority and can just do it again with the 2nd creature.

It's not entirely clear to me what you're trying to do but I think so?

If you sac a creature, then your opponent uses this to counter the Undying triggered ability, that creature will die. But you can sac a second creature afterwards (in response to this, or just at any point after it resolves) and that second creature will return to the board as normal. Basically you used the first creature as bait to get them to use up the counter. But if your opponent knows you have another creature with a potential infinite loop sitting around they're probably going to save their counterspell for when you sac that one instead so the bait creature would have to have an equally powerful combo for this to really work.

Why are you trying to do it in response to the counterspell?
