What do you need:
x1 God Card
x50 Cards of any doom, except Gods and opposite Doom (Minions, Fates and Relics)
x10 "Mana" Cards (Any doom except opposite Doom)
How to setup:
First, separate the chosen god card and put it face up, in front of you, at a safe distance so you can play your cards close to you.
Second, separate the cards regarded as "Mana". Shuffle them and put them face down, in a pile.
Third, shuffle all the 50 cards and put them face down in another pile.
Fourth, the god draws 4 cards and put them face up.
How to play:
The god is treated as another Endbringer, with some exceptions.
At the begginig of each round the god buy 1 card from it's main deck and 1 from the "mana" deck. If there are no "mana" cards left, it draws 2 cards from the main deck, as usual.
The mana card is automaticaly played as mana.
The god can double any mana generated from a mana card from his own doom.
When playing a minion, except from *purple* and opposite dooms trigered effects, all effects trigger as if the minion is of the right doom.
When playing a card from a doom that is not present as a mana card, the god can pay twice the cost to play that card.
Gods play minions every turn if able. Fates are secondary, only played when the God has run out of minions. Exception: When a fate would prove essential to prevent loosing or to earn victory.
When playing minions, the god creates and focuses on increasing the size of it's abominations.
At the begining of a turn, the god can exhume a card from the graveyard.
