I have two main thoughts when I read this card
We just don't have the tools to interact with the stack, and our sideboard is more geared toward graveyard decks and control than combo
There are a few in here that will let us copy Hinata, which might lead to some very silly battlefield states, especially in casting stuff for less
His +2 ability untaps two target lands (totally not broken when paired with Badgermole Cub), while his -3 creates a 4/4 green Beast creature token with Trample
Each Saga enters the battlefield with a lore counter on it, causing the first abilitythe chapter I abilityto trigger
Though having said that, some of the cards I thought looked awful online, like Rhystic Study, actually looked way better in person
