Typhon, the Infinite Monster
You cannot have cards with
in your deck or magic stone deck.
You cannot have non-darkness cards in your deck.
You have no maximum deck size, but must have at least 100 cards in your deck.
If you would set your starting life, set it to X00 life instead, where X is the total number of cards in your deck, up to a maximum of 200.
And therefore began the infinite duel.
