Currently my first list of a Diabellestar/control strategy. Deck is very flexible and rarely have I seen dead hands. Diabellestar send any Golden Land/Cursed Eldland for value (or Hidden City if you REALLY need to). Threw in Dragoon since you can Red-Eyes Fusion then still set up Guru/Fiendess while activating Red-Eyes Fusion in the turn.
Diabellestar can also revive itself on your opponents turn when you discard it as negation from Dragoon sending any useless Eldlich S/T or other card you don't need.
Extra deck and siding can be whatever you want. The most common extra deck monster i'm using is between Dragoon, Black Luster Soldier and Vampire Sucker but none are required except Dragoon really.
Give it a try, let me know what you think. I've also got a Orcust Diabellestar list, and a Fluffal Diabellestar list if anyone is curious to see them.
