Phantom Knights

Level 3 DARK Warrior Xyz into Dark Requiem Xyz Dragon, Rusty Bardiche setting Fog Blades, and 3 Dominus Impulse. Maestros adds Dark Rebellion Xyz Dragon, Four Heavenly Dragons (2 Level 4 DARKs; on summon destroys an equal number of cards on each field; when you activate anything, detaches to Xyz over itself into any Rank 4 DARK, e.g. Evilswarm Ophion). The deck fuels itself by banishing its own GY, which changes which hand traps are safe.
