mjolnir mtg card Mjolnir, Hammer of Thor | Marvel Super Heroes Variants Foil Double all damage equipped creature would deal. Mjolnir, Storm Hammer (Foil-Etched)

Discarding cards is barely a cost, especially with cards like Inti, Seneschal of the Sun and Containment Construct that turn it into card advantage

Drawn To A Fight does help you play John Silver a little faster, reducing the cost down to just six if an opposing character was damaged this turn

You dont really want to kill some random Kor Soldier token, but how many triggers of Umezawa's Jitte can you give your opponent

Explore gives you a lot of lands, lands let you use eternalize abilities

So I think I'd like to keep it as a 2/1, however if it was created in a format that contained gut shot or something similar, I would up it to 2 toughness
