"Dark World" cards are generally intended to gain advantage by activating Summoning, destruction, and other effects through discarding cards (through effects) from your hand into the graveyard. Many "Dark World" monsters gain extra effects if discarded by an opponent's effect. They are based around effects that activate when they are discarded from the hand to the graveyard by a card effect. The "Danger!" archetype aims to amass card advantage from the effects of the "Danger!" monsters, that force the opponent to discard a card from the "Danger!" player's hand. The strategy consists in the "Danger!" monsters revealing themselves in their owner's hand to activate their effects, then "hiding" in the hand again, making the opponent randomly discard a card from their opponent's hand. If they fail to "catch" the "Danger!" monster, the monster is Summoned and a card is drawn. If they do "catch" the "Danger!" monster, it triggers its discard effect, which varies from Special Summoning a "Danger!" monster from the Deck to destroying a card on the field. As such, the competitive potential of the Deck lies in the fact that activating a "Danger!" monster's effect will only rarely be a disadvantage to their user. Summoning several "Danger!" monsters in a turn isn't difficult and they can quickly perform an OTK, especially when combined with other archetypes, such as "Dark World", whose effects activate when they are discarded.
