Notes & Combos
Summon Electrumite --> grabs Sorcerer. Pendulum summon Sorcerer & combo into Vortex Dragon with Verte DPE.
Then layer more interruptions with Promethean in GY & Pendulumgraph for more pops.
Also, DPE combos well with both Pendulumgraph & Promethean Princess. Since you can basically chain DPE onto the same target & both will go through.
