Kashtira Raidraptor Dragon Ruler

This is a very WIP deck centered around summoning D/D/D Duo Dawn King Kali Yuga. I've always wanted to use the D/D/D cards competitively, and I think this is the way to do it (I'm ignoring High Caesar in Fiendsmith on purpose).

General combo: ANY 2 7s makes Kali Yuga on the opponents turn, here's how;

2 7s into Raidraptor Arsenal Falcon (Kashtira sometimes XYZ locks you, that's completely fine for this main line) -> Detach 1 to summon Tribute Lanius from deck -> Tribute Lanius effect send Raider's Wing -> Raider's Wing detach 1 from Arsenal to Special itself -> Overlay RWing and TLanius into Raider's Knight -> RKnight effect to xyz into Brave Strix -> BStrix eff detach RWing to add Magic Launch -> Set Magic Launch and Pass (after doing any remaining plays, of course).

The moment your opponent does anything in the Main Phase, activate Magic Launch and overlay Arsenal into Kali Yuga. 

Congratulations, you now have a Turn Skip (kinda).

If you draw Raider's Wing, you won't be able to make Yuga (except for random niche scenarios I won't mention). If you draw Tribute, you can still do it of you are able to get out 2 7s without your normal. You'll need to make sure you can detach a material from the R7 you make though (There a various methods, depending on the scenario).

 End goal of this deck is to either Turn Skip into a OTK (Kali Yuga has 3500atk, after all), or enter a grind game and use DRulers and cards like Kashtira Birth and Promethean Princess to outlast your opponent.

I DO NOT recommend this deck for play in the TCG as of current. Due to the existence of Maliss, Artifact Lancea AND Dimension Shifter (especially the former) see heavy play, Lancea kills the entire deck and Shifter kills our Kali Yuga line.

If you're up for a challenge though, have at it ;3
