Say I were to set aside my heroes - including David the Contrite - with Passover & Unleavened Bread (Pi). My heroes then return to territory. I bounce David the Contrite, then play him as David, Heart After God. I then attack with Dave HoG. Does Passover & Unleavened Bread activate? If P&UB granted the hero the ability on return, like Provisions, it would be reset. However, P&UB seems to be an ongoing ability that triggers when a targeted hero enters battle. Will I get the underdeck? Does it matter if I use David, Heart After God's ability to convert him back to David the Contrite?
