Dark
During your Main Phase: You can discard 1 "Dark World" monster, and if you do, "Dark World" monsters you currently control gain ATK equal to the Level the discarded monster had in the hand x 100, until the end of this turn. If a monster whose original Type is Fiend is discarded from your hand by the effect of a "Dark World" card or an opponent's card effect, even during the Damage Step: You can discard 1 card, then draw 2 cards. You can only use each effect of "Dark World Archives" once per turn.
