During either player's turn, when a card effect is activated in your opponent's Graveyard, you can send this card from your hand to the Graveyard to negate the effect.
These are some of the cards that are used in current meta decks that can be countered using Skull Meister’s effect.
All these effects are negated by discarding Skull Meister.
