>>87964618Labrynth is an eternal Tier 3 deck that will continue getting support, while Centurion has upcoming support and also works great as an engine. There's also Mikanko which can be built for both going first or second and its current variant plays a special summon lock on your opponent. Then there's the whole Sinful Spoils storyline, MD will soon get Diabellze, White Forest and Azamina.
I also own both Live Twin and Dragonmaids, the former has been powercreep to hell without proper support, but still works fine mixed with Sprights, while Dragonmaids is very outdated, but they're about to get new support in the next Quarter Century box, so you can look forward to that.
>t: started Master Duel just to play cute girl decks
