If you choose the second mode and one of the two cards leaves your graveyard, you'll still return the other card to your hand as long as it has a creature type that the other card had as it left your graveyard
Scarecrone One of the few cards that interact with scarecrows, Scarecrone is a functional yet slow sac outlet and reanimation package
Good news, because Kenrith, the Returned King is the MTG commander for you
It also has the upside of being able to be cast with your creatures due to having convoke, so at times youll be able to cast it for effectively zero mana, which is absurd
Where it really shines is in decks that have three or more mana types, as Reflecting Pool can help manage the many mana colors alot easier by giving an additional mana of the specific color you need
My gut tells me if either of these decks comes close to playable in cEDH, itll be Fae Dominion
