What is purple mana supposed to represent?
In Hellscube, purple mana is the sixth color. Unlike the other colors, you can’t add basic lands that produce purple to your deck after drafting (purple basics are called Nebulas), meaning that if you play purple, you have to draft every purple mana source.
Mechanically, it’s the wackiest/most “out there” color, doing things that even other hellscube cards wouldn’t. It often deals with sideboards, zones, and phases.
Thematically, it is tied closely to space, aliens, cats, and clowns.
