Seems a little OP, just a little.Might want to consider making it not cost chroma but a element instead? It is chroma because I did not want to make it simply a more expensive Pandemonium. Might bump the cost a bit.
Wait a min~Plague -> DeathBlack Hole -> FamineFire Storm -> WarIs Pandemonium going to embody Conquest? For better or worse, yes. Also we could take Fire Storm for Conquest and Pandemonium for the chaos of War.Also, unupped Pandemonium affects your field, while upped ones do not. Which one will Four Horsemen/Apocalypse possibly inflict?Apocalypse is all upped spells, so it definitely only affects opponent's side. I think unupped could get away with affecting only the opponent's side, but it could also serve as a russian roulette element for the spell.
with this name i kinda want to have it do all at once instead of a random one (would cost around 9 i guess)
