Notes & Combos

Shoutout to @myugioh YT channel! I basically followed his decklist with some minor modifications. I added Sapphire to deal against BS (Bagooska-Starliege) Ryzeal endboard. The idea is to make Aquamarine, summon one Gem-Knight monster, then link into Phantom Quartz, and use Aquamarine's effect to spin Bagooska.

I liked @myugioh's idea a lot, especially because the synergy of Orange Light with Fairy monsters in this deck (even with Lancea, as you can send it as cost for Orange Light's activation). You can also use it as a fusion material if needed.

This is the first time I ranked using a going second OTK Gem-Knights deck after previously using Tenpai. I decided to go with Gem-Knights because it can be played similar like a Tenpai deck with boardbreakers.

Even though I managed to reached Master V before the new pack comes, I actually struggled a lot. This included consistent deranking from Diamond IV to Diamond II and from Diamond I to Diamond II.

I previously used a Super Polymerization build, but turns out it was quite bricky. And often times Super Poly does not really solve problems against Maliss because they can still rebuild their board during the opponents' turn.

I am certain this decklist can be improved. I never summoned Dugares at all throughout my games. Dugares was planned to be the ATK boost for Master Diamond. I am also thinking of cutting Meowls because it does not really provide good value in my games.

Aside from Maliss and Ryzeal, one of the matchup I struggled hard was against Tearlaments. IMO, they have much more utilities to interrupt going second plays compared to Maliss and Ryzeal - Snow and the shufflers are my worst nightmares against Tear.
