Notes & Combos

Change Illusion Gate for something else if you want. This meta with Kewl Tune is awful for going second decks, and every meta deck has floodgates to abuse, it's still doable with Gem-Knight as it is very resilient deck but it is very annoying and frustrating to play.

Started the climb to M1 about a week ago, deranked 2 times in Diamond and after failing to win two rank up games, I went from M2 to M4 in 10 games once where I couldn't even get to Master Diamond Dispersion. This season I barely managed to resolve handtraps, everyone had Maxx C glued to their hand and Gem-Knight Fusion was glued to my hand.

If this is the way Konami wants the game to go, with million negate and interruption slop decks, turn 0 plays, new archetypes looking at your hands for no cost and drawing multiple cards, indirect support for overpowered archetypes, then there's no wonder why we are seeing record low numbers on MD, just unban and unlimit all the old decks from Kashtira to Tenpai...
