Everyone is playing Skull Meister to counter most graveyard decks. Just to tell that in the ladder, you don't need such a tech. You just ruin your deck by doing so.
Skull meister backfires against Anti trap decks. Plus Anti trap mostly counters AGs even reactor dragon but can be useless against survivals end and lavals by backrow demolition
But, I'm already KOG and I faced those who used it against. One guy was lucky and was able to drop 3 Skulls to disable my Vampire plays, others just drop one and lose afterwards. I'm the one who posted btw, and my deck is the post ban Vampires
