The ability will resolve before the spell that caused it to trigger, and a token will be created even if the spell you cast was countered or permanent it was targeting is now an illegal target
Final Fantasy II Firion is sort of the "main character" of Final Fantasy II
Lion Sash The white Scavenging Ooze, as I like to call it, has about the same abilities as its green counterpart
Then theres Brotherhood Scribe, a creature that can tap to gain an energy, but you can only activate it if you have three or more artifacts, which wont be hard at all
Note theres a bit of overlap between BR and WB, so you may be able to splash Unexpected Request for treason and sac lines
Izzet Prowess might not need it in Standard, but I wouldnt rule it out either
