Used Chaos Wand, and the targeted card ended up being Isengard Unleashed (has Flashback).
Cast Isengard Unleashed using the effect of Chaos Wand.
Isengard Unleashed goes to the opponent's graveyard, but still gives me the option to cast it from their graveyard for its flashback cost...
Am I missing some weird interaction or ruling and it is working as intended? Or should I not be able to do that? 😅

: Target opponent exiles cards from the top of their library until they exile an instant or sorcery card. You may cast that card without paying its mana cost. Then put the exiled cards that weren't cast this way on the bottom of that library in a random order.
