This in-progess set (current working title: Initiative Sequel Set) is a Commander Draft set featuring two new dungeons shown here and new Backgrounds. This set has an artifact theme plus two new mechanics. The first new mechanic, galvanized, is prominently featured in the Blue/Red Instant and Sorcies faction and says: This creature gets +X/+0, where X is the number of instant and sorcery cards in your graveyard. The second mechanic, repurpose, is for split cards in the style of the Aftermath keyword. The first half of the card is a creature, the second half is an Equipment with the keyword repurpose that allows it to be cast from the graveyard.
The cards and dungeons shown here are my first drafts for all of them so there will very likely be changes made for balancing. If you have any feedback I'd love to hear it! Below are links the cards I've finished so far.
