I basically am using mana. there are three types of genre cards. Forge, Engine and Space

So mana cards are named acordingly (Mana: Forge, Fuel: Engine, Distance: Space)

I didnt like how, in magic, mana stays on the field. In this one, those cards are destroyed when used (mana summons portal, fuel is burned, and Distance is jumped to)
