Time paradox: You don't sacrifice stuff until the spell resolves, but you have to know how many modes you choose as you cast the spell.

Time to sacrifice some "permanwents" xD

Anyway, my suggestions would be either to go with "Choose target player, then sacrifice..." at the start, which locks the card into targeting one opponent - or go with "An opponent loses..." etc with each modal thought that's a bit questionable. Maybe "Each opponent discards..." wouldn't be too overpowered?

The "correct" way to do this is "as an additional cost to cast this spell, sacrifice any number of creatures." Does leave you open to blowouts, though

The etymology of typos. If it's in play, it's a permanent. If you can sacrifice it, it's apermanent. Once you have sacrified it, it's a permawent.

This is a high risk, very swingy card. That's fine. If you have 7 token creatures, you deserve to be able to break a ground-stall and fling them all at an opponent. And if they manage to avoid it, you then deserve to lose :)

But it's probably a bit cheap for that potential usage. I'd suggest it either have a built in limit (of, say, 3 creatures?) or gets the cost increased a bit.
