Can I use Pride in the Flesh to release and band to demons from Tartaros (PC)?
Pride in the Flesh - [X is the number of Opponent's Redeemed Souls] - "Interrupt Kingdoms of the World. Release up to X demons from an evil Fortress and band them into battle."
Tartaros (PC) - [Plays to Set Aside area, Holds any # of demons] - "If your demon is discarded or captured, you may hold it here instead. If your demon wins a battle, you may underdeck a demon from here."
