Notes & Combos
Orcust does a great job at complementing PK, while true the build produces some awkward hands with multiple normal summons, the ability to further extend is just way too valuable. Orcust here is somewhat similar to what Fiendsmith is in other decks, an easy any-2-bodies bridge that spits bodies which can then be used to make Rusty Bardiche.
It adds starters that play through handtraps, removal both for OTK going 2nd and as endboard piece interaction with Dingirsu, Crescendo which nulifies any funny breaker the opponent might throw at you, extension with Mermaid, is just a lot of good stuff.
