Recommendations to turn this into a ladder deck: remove ash blossom and replace with board breaker of choice. Dark ruler no more is the best one so you can use gungriur and trishula to destroy their monsters. Replace phoenix with stardust shooting dragon. Remove one moray and 2 crystron traps, and remove one smiger and add winds over the ice barrier, zujin, and general raiho. Idk why I never did this

I know this is late but omg this deck is god awful it needs so many updates I will try to reach masters with a new deck, if I can even rebuild this competitively

I just want crystrons to see some play... :( trying out so many vers like danger-auroradon, undine starter, new white aura cards but nothibg rly seems to be good enough for this meta

Ice barrier seemed good till the amount of locks it and crystrons have. If crystrons just had an okay one card combo that does not lock the entire archetype could be saved.

Randomly remembered this decklist. I assume you havent had any luck with trying to create something yet. I mean lancea and Raiho lock seems solid but i also still struggle to find a use case for crystron. Esp using their accel synchro effects thst are locked behind mid machine synchros. My best use case is still auroradon turbo but yeah. Just wanted to check in lol
Oh also those new ocg crystron cards look like new hope. I hope to see them soon in md tho it seems like even with the new cards their boss synchro monsters (ametrix, quarion, quan) are still mid which makes me sorta sad but it is what it is
