I've been having so much fun with tag force special that i missed out on a day of gems in master duel, which isn't really a big deal, but since i'm scrounging up resources for ryzeal i really shouldn't be skipping on dailies.

This is what i'm running right now, it's a shitty EARTH machine deck, basically you spam level 4's until you can make GGX, then you search tin goldfish to summon a generic R4NK (including motherfucking shock master), or gearframe to search fortress.
Sometimes you actually get two level 7's on board, which allows you to xyz summon big eye (monster steal) or dracossack (can pop cards, can't be dealt with unless they deal with its tokens first), but that's basically it, it has no fancy combos or convoluted playstyle, it just generates resources and uses them appropriately.
None of my monsters are particularly big, but fortress can "trade" with anything by ramming itself into it, and i have quite a few tools in the extra to deal with a lot of threats (silent honor ark, castel, exciton, roach, blackship of corn) that i can't or don't want to run over. Still, i'm packing a shit ton of removal because the AI can be incredibly gay at times, 1 dark hole and 1 heavy storm isn't enough.
The only thing that i'm missing is a R4NK that works like utopia the lightning, basically anything that can't boost itself to close out games, but AFAIK there's nothing like it that came out in the early years of pendulum.

Not sure what i'll build next, probably qliphort since i'm also building the deck irl, even though it was slow and bricky 10+ years ago.
