Notes & Combos

Fought for my life for 5 days since i kept bricking with VSK9 so i swapped to my other all time favourite archetype: Crystrons!

The deck feels amazing to play with Noroi being a 1 card starter, Jokul + Sulfador being the most broken combo to start your combos and just having answers to spell/traps that VS doesnt have access to being Dragster + Infinity.

Im on 2 tristaros as cluster can only recycle so many cards in a normal game and having 2 is not bricky as going 2nd NS Tristaros is always threatening a dragster summon if they activate an effect or at worst removes a negate/ash blossom from their hand.

Handtraps speaks for themselves + drolling urself is viable in this deck unlike VSK9.

ED is pretty solid. Was on 1 ripper with ty-phon but ty-phon feels very fake and i at time kept wishing i had a 2nd ripper and it worked great! Jacks is also great going 2nd to help break boards.

DO NOT PLAY SPELL CANCELLER. Toxic floodgate + it really doesnt do all that much for the amount of resources u need to bring it out + its bricky! But hey who am I to tell u what to play lol

Overall, the climb wasnt the smoothest but there were many fun games along the way :D
