Lets take a look at those changes first
Then you can discard two cards at the beginning of your first main phase to return this to your hand from your graveyard, which is card disadvantage naturally but with madness, lands, discard triggers like Archfiend of Ifnir, and loads more, it's got value
While some split cards let you cast one or both sides in the same turn, there are split cards with an aftermath mechanic where you cast one side, wait for the card to hit the graveyard, then cast the aftermath portion
It's part of a cycle of rare enchantment creatures from the Duskmourn MTG set which all return to the battlefield as non-creature enchantments after they're killed, making it a nightmare to remove
Dont forget to include infinite hand size resources like Wizard Class and Reliquary Tower so you can keep everything you draw and not have to discard down to hand size at the end of your turns
