Notes & Combos
Exosister deck with a splash of Buster Blader. The softlock is very easy to set up and can be very disruptive to most decks especially if you get it out during their Draw or Stand by phase.
To get it out simply normal summon Whelp, search out Prologue, go into Almiraj and then on their turn activate Prologue from the field and send Memories and a Buster Blader. This will let you summon Buster Dragon and you can activate Memories graveyard effect to special summon Dragon Destroyer which will prevent all of your opponents monsters on field from activating any of their effects and going into monster-type specific Extra Deck monsters.
Rest of the deck is just basic Exosisters.
Have fun!
