Exosister build with a splash of a Buster Blader core!
It's pretty fun and allows for alternate routes. Buster Dragon turns every monster on your opponents side into the Dragon typing which can be disruptive when they need to use specific monster types for extra deck plays. Exosisters are able to go into rank 4 monsters pretty quickly especially with the help of the familiars.
You can soft lock your opponent by just starting with a single Whelp. Simply normal summon Whelp search prologue and go into Almiraj. Use prologue on your opponents turn to target Memories and a Buster Blader to go into Buster Dragon. Then you banish Memories and use the Whelp from your first turn and the Blader to summon Dragon Destroyer.
With this, your opponents side is soft locked and they will have to spend resources to get rid of your field or end their turn if they are heavily relying on activated effects from monsters.
Still playing around with the build and changing it as I go.
