Cards that are officially spoiled so far can be found here

If at the beginning of your end step there are more than 8 cards in your graveyard, the enchantment flips and becomes a 4/4 creature with flying and Crew 1, which allows it to become an Artifact creature until end of turn

Cute with Enrage, sure, but, Raging Swordtooth costs the same amount as Regisaur Alpha and Charging Monstrosaur, to say nothing of Glorybringer

Of course, this means you need a character on board that can initiate the challenge before Maid Marian gets value, but there are 11 4-cost characters that all have decent Strength values, so it isn't hard to get something down the previous turn that can take the Challenge

But you could pull off some tricks with Scrump, Binding Contract, or Food Fight!/Sherwood Forest Outlaw Hideaway to make him a not-bad card
