Phantom Knights Mitsu

To access Mitsu engine: 2 PKs into Cherubini, Cherubini sends Fiendish Rhino to grave, Fiendish Rhino sends Archfiend to grave, Archfiend sends Mirror to add Habakiri OR 2 PKs make Contract Witsh, discard a spell to add Habakiri;

To access PK engine: full Mitsurugi combo to make all 3 on field, 3 dark monsters to make Bardiche, Bardiche sends Cloak to grave.

Foolish to send Fiendish Rhino to access Mitsu engine OR Foolish to send Cloak to access PK engine.

This list is perfect for using both Dominus Impulse and Spark, Infestation Pandemic is great to protect Ophion from spells and traps, the PK rank-up spell Launch could be great if shamanite is planned to be ranked uo into Ophion/Nightmare/Karmael, but the rank up spell Force is more versatile because it can be used even if the xyz monster still have its materials (something negates shamanite on summon, Ex: veiler)
