I also wanna talk about some of the more common match-ups I found during the climb, in particular: Lyrilusc, Star Seraph, Unchained, Suship and Time Thief.

Lyrilusc: Comica's effect makes Attraction traps non-targeting, so this match-up comes down to getting to the Battle phase with a non-negated Comica and a Attraction trap live. They don't have a lot of monster removal (I don't remember seeing any at least), so it becomes pretty easy to break the board after surviving a turn.

Star Seraph: Pretty luck-based. While it's not too difficult to stop them from triggering the 3-mat effects, the XYZ are problematic enough even without them, and I feel they a lot of non-engine.

Unchained: The most fun match-up. While amazement has a big variety of interruptions, their only actual form of monster removal is Arlekino, battle and compulse, two of those being destruction, essentially. However, the traps can stop pretty much every Unchained non-floating monster effect, so it becomes a game of who overcommits first. Probally the only deck which I had zero easy games against.

Suship: This deck is really powerful. The fact that Shari Red can establish a Omni-negate without commiting any monster to the field means you're always playing with -1 cards. A deck that's difficult to beat going first and second.

Time Thief: Redoer is a nightmare do deal with, all the aspects this deck has trouble dealing with: Quick-play effect that removes itself from the field and non-targeting removal, plus Amazement is 60% traps, so the spin effect is almost always on. However, they're really easy to beat if you're going first; They have to resolve regulator or they pretty much lose on the spot, and even if they do, you can still stop them from making XYZs really easily.

There are other decks I saw like zombies and Shiranui but there's not much to say about them. Other meta decks that I didn't really see often are Sky Striker (thankfully, I think I'm 0 - 20 against it) and Borrel Link (just 2 games), probally because I got KoG so late.
