Notes & Combos

I literally scrapped this deck together for the event

  • Realistically i would want to play more handtraps rather than droplets or lightning storm but i dont have any

  • I just link climbed into terahertz and smacked them for 11k

  • link spider or dark templar didnt come up once (idek what dark templar does lowk i js saw another guy use it)

  • I would use Decode talker but once again i didnt want to use any UR dust for this event

  • Diameter, ttt and a few more cards was useless

  • i ran nibiru for a bit but i dont have anything to out the token so if you have accesscode id run it with nib
