Yikes, why did nobody summon me to help here. I'm pretty sure I'm the resident Phantom Knight expert. Alright so for starters, you don't need three rank-up spells. Two tops. Remember that you aren't trying to draw into it, it's searchable whenever you'd be using it for the standard combo. Opening it is a dead card, so even two is a little greedy, but it can have its uses. Also with that many slots in your extra deck dedicated to the Rank-Up, you'd be better served taking a couple Requiems and one Rebellion out with the 1 RUM, and replace them with Rhapsody+Requiem in Berserk.
Honestly, this deck is ALL over the place. Placing these two engines together isn't so much going to help them out as it is just hinder your Phantom Knight side whenever you see Fables instead of them. The RDAs aren't gonna help you, gotta get some links in there too. Too many PK traps. The Pots and Returns gotta go. The level 4 PK isn't gonna help here either. The 1 of Solemn Strike is weird and could just be a Judgment. Honestly if you don't want to just run the PKs with BAs then you'd be better off sticking them in Lightsworns.
Overall, while there are methods to making it work more efficiently than it does here, this deck as a whole isn't salvageable. You're better off starting over with a different engine mixed with the PKs if that's your goal here.
