I have been constantly faced with a glitch when playing ranked matches. I use buster blader, with hex light sealed fusion as a substitute. I play on both mobile and pc. The following glitch has been happening ONLY on the pc version: When I try to fusion summon with "destructive swordsman fusion" using a dragon type (in my hand or field) with the hex monster, I am unable to do so (as if some requirement has not been met). I have had dna surgery placed so that every monster is dragon type, yet I still cannot fusion summon with hex using the quickplay fusion spell card. It only happens on PC. Please look into this.
