I dont understand all of you saying crystrons are so popular or so broken. KC report clearly shows that NOBODY uses crystrons. If they were as used as you say they are, Ametrix would be on the list of most used extra deck mons.
And even in the last KC cup where it somehow showed up in the top 100, i neverrrr saw them while dueling in stage 2. Either they’re all just so highly skilled that you don’t encounter any below 20,000 DP, or there actually aren’t a lot of crystron players at all
Consider yourself lucky for not pairing against any of them. Based on the data here, Crystron was the most used deck in the last KC Cup by the top 100. Forget about all the Shinarui abuser. Shiranui just cannot compete at the highest level.
You just don't understand, Crystron is the most expensive deck in the game and you need 30 cards to play it.
Cybernetic Rebellion - All core cards + 3 Sulfefnir 15000 gems
3x Wheeleder - 10000 gems
3x Genex Undine - 15000 gems
2x Thystvern - 7000 gems
and you need 3 Cosmic Cyclone, SSA, Coral Dragon, Black Rose Dragon... Where the hell beginner can get so many gems to invest in 1 single deck?
Shiranui is the most popular deck because it is cheap. Yes it is one of the cheapest deck, you only need to dig 2 mini box for all the monsters. Less than 8000 gems to be exact. Then use all your URs & SR dream tickets to get broken traps to complete the deck.
You can only play Crystron if you are a p2w or if you are lucky enough to pull everything you need from a box within your first 30 packs.
