I think I've got a decent start for a decklist...I call it (the start of) Lucky Gemiknight!
3x Gem-Armadillo
2x Summoner Monk
3x Gem-Knight Amber
2x Gem-Knight Iolite
2x Gem-Knight Sanyx
2x Gem-Knight Obsidian
3x Volcanic Shell
3x Thunder Dragon
3x Gem-Knight Fusion
3x Gemini Spark
...and that's basically all I got for the main deck. Summoner Monk dumps Gem-Knight Fusion (GKF) to get something out, Xyz into something, detach a material, then banish that material to get GKF back. Slowly set up the graveyard for the play I mentioned earlier involving getting out 3 Citrine in a single turn. Or get out Prismauras to blow stuff up.
