The only thing that Japerrot only doesn't work with is Outlaw. But Japerrot is designed to be a quick serious stab and is disposable, so it's fine. Gambit is something that needs to be tested, admittedly. Vorpal Spartar is a risky card to remove, but if push comes to shove, then it shouldn't affect the deck if it is moved into the side.


 * The point you've said about Parade of a 100 Demons is correct. We should wait until all the Hundred Demons for the next set are revealed, before making a definitive list on a deck based around the Buddy.


 * As for Ein, I just got the idea for using Boomerang+DRS as a gauge engine, and then using that new Impact Dragon Secret Technique, Dragonic Resurrection to Superior Buddy Call Cocytus multiple times, so we can do it up to five times, for free. Also using Dragon Throne to use the size 2s of Ancient, plus the defense of Dragon.


 * Idk, an Ein Deck just seems more prospective that a pure Ancient Build. But as far as the Ancient one goes, it's just down to nitpicking, as the overall build is good as a base.


 * Also consider Rise & Fall of Dragons, which is normally a staple for the deck at 2.
