Synergy

Chaos End Master
Level 3
When it kills a monster special a level 5 or higher monster with 1600 or less ATK

Sphere of Chaos
Level 5
The usual target for Chaos End master.
BUT! When its tribute summoned, you can search a level 3. Either Chaos End to synchro next turn
because it can survive one attack or...

Dandylion!
Level 3
The token spawner

Quickdraw
Level 5
Another target for Chaos End Master!

So...
Chaos end Searches Sphere and Quickdraw
Sphere searchs Dandy and Chaos End

It might be bad to summon a level 3 tuner and level 5 tuner at once, but if you have some tokens or something it shouldnt matter.
Foolish Burial.
Level Eater.
Quillbolt.
Instant Fusion for just Chaos End. Synchro, then pop a level eater out of the grave.
Hm, that seems like it needs a lot of setting up, but the formats slow enough for it.

Cookie Cutter Decks

I summoned Stardust and my deck got called a cookie-cutter deck...

It was a Chaos-End Cyber Dragon deck...the hell?
