Beyond introducing powerful reprints like my personal favourite, Rise of the Dark Realms the game also introduces a raft of strong new Equipment cards, more removal spells, and cards that provide great reward for slinging spells
Lets focus on that strategy as one idea for a rework
While a melded permanent is on the battlefield, it has only the characteristics of its combined back face
That damage is going to add up fast, and there's more ways to empty your graveyard in red than you might think
It might not be a Game Changer in Magic, but it certainly was for Final Fantasy
Sorceress's Schemes is a red uncommon that pulls other instants or sorcery cards out of the graveyard or even exile, and - with the right helpers - creates an infinite loop that will ping your opponent to death
