Im not really vibing with it

For the reasonable cost of three mana, when Urza's Incubator enters the battlefield, its controller chooses a creature type

Being able to pay 2 mana to make and sacrifice a creature with no other costs can become very powerful with cards like Grave Pact and the new Martyr's Bond, which unfortunately comes with the Political Puppets deck, not this one

Gush is one of those odd support cards like Frantic Search that is most abusive in specific combo decks but still has a sufficiently generally useful effect (drawing cards!) that you can play them most places

While their proxy boosters are very novel (as far as I know they and PrintingProxies are the only ones that do this), I would say they are best known for their ability to print and ship out any large list of cards you want, on demand
