Notes & Combos

You can add more copies of Mathmech Sigma and Diameter for more consistency (since they are both skill triggers) if you have them

You can take out Detonate Deleter and put S-Force Justify instead, and you can cut Cyberse Wicckid for another Splash mage or a link of preference that could work

Also, as a tech to play around things like Droll & Lock Bird, dont use Circular's 2nd effect inmeadiately, wait until you summon Primathmech Alembertian, to search with both, therefore dodging Droll completely
