Notes & Combos

Blind second Gem-Knight. The Dracotail/Yummy meta is much more forgiving than the Maliss reign of terror, but the climb in master was still pretty rough. Ended on a 60% win rate in master, but the last 20 games were 14/6.

Matchups: The hardest matchups were actually Lunalight and Blue-Eyes. If BE went full combo, Sifr being able to invalidate your board breakers was pretty brutal. I put in Light Dragon for the Lunalight matchup, but it never actually worked out. You can beat a single Liger easily, but for two you need to perfectly set up the GY so Master Diamond can get big enough to get over them. It's not easy but it's possible as long as you don't use Phantom's effect.

This deck chewed through Dtail pretty easily. Red reboot almost entirely shuts them down and even without it, as long as they fail to draw relevant hand traps they can't stop you. Yummy is harder, which is why there are two Sales Ban. Sales Ban call Snatchy is devastating for Yummy and it's almost impossible for them to stop you after that. The card is also great for eating a negate like Herald or Baronne, and calling a key card like Faimena can force it early.

D/D/D was actually the third most popular deck on the climb. Their endboard is very hard to play through without droplet, but they almost always put most of their stuff in attack position, so lightning storm or raigeki will clear them entirely. Raigeki came in very handy vs. them and Yummy, so I'm happy with that choice.

Extra Deck: Every single fusion came up at least once. Lapis even won my master 1 rank-up game. Lapis and Aquamarine came up the least, but they were both very useful in winning certain games. Light Dragon and Phoenix are flex spots. Phoenix won me a couple of games, but the theory of Light Dragon never worked out. Tried Donner and Little Knight for a while but didn't like either of them.

Ash was my biggest problem for the climb. Ash on a charmy or on my extension after breaking a board was a deciding factor in way too many games. Having to start with one less card against a full board because they got lucky and drew Ash was often a death sentence.

Overall this was a very fun deck for this meta. Created a lot of really interesting and complex duels for a blind second deck.

Rank up game against Yummy was the best one, imo. Basically an anime duel with Ash getting put down in the end for some personal satisfaction. Others showcase some really good clutches for the deck through what seemed like impossible odds.
