The same is true for creature spells you control and creature cards you own that arent on the battlefield
It's a little vanilla but could be the start of a great budget brew
The Disney100 Editions, ostensibly part of Disneys 100th anniversary as one of the largest media conglomerates on the globe (with a franchise sublimation inertia that reminds one of a black hole), will also include four Rise of the Floodborn booster packs
When this creature leaves the battlefield, return the exiled cards to their owners hands
It places a triggered ability on the stack at the beginning of the end of the extra turn you take that causes you to lose the game upon resolution
Heres how it plays out: You are required to have The Gitrog Monster out, Dakmor Salvage in hand and more than 7 cards in hand total At the end of the turn, discard down to hand size, discarding Dakmor Salvage This gives you a draw card trigger from The Gitrog Monster Priority passes to opponents On resolution of the draw trigger, replace this with the dredge from Dakmor Salvage, milling 2 cards and returning Dakmor Salvage to hand As it is still the cleanup step you still need to discard down to 7 cards in hand, again discarding Dakmor Salvage and repeating the combo above on a loop The idea is you loop this to fill your graveyard and try to win from there
