Notes & Combos

This is my earliest Master I that I have achieved after several season playing Tenpai, using going second Gem-Knights. Never thought I would be able to do this quickly.

I switched to the more standard build instead of my previous one with Orange Light.

After the release of the new pack, I was contemplating whether I should replace Lancea with Droll. I just keep playing from Master III onwards and found that Maliss I still got matched against Maliss quite often, therefore I decided to keep Lancea.

The climb in Master was quite smooth. I managed to face two Mitsurugi decks during my climb. However, it seemed that both players were not able to setup their board optimally. I never played TCG, so I did not know how their endboard should have been. But I just keep in mind that Murakumo has to be handled immediately. Maliss and Ryzeal were still the dominant decks on ladder.

I decided to keep Sapphire as a way to enable me hard making Aquamarine and deal with problematic cards (that can be targeted).
