Hi Guys, I've noticed some errors in these cards and I've tried to fix them (and succeed), the first error concerns mirror force dragon which does not activate its effect ("<" and ">" were reversed and a subtraction gave negative values), the second one concern Doom Virus Dragon because it's continuous effect, that checks the set monsters, slows down the game since that executes the action at any time, I changed the script so that it checks when a monster is set and when the dragon itself is summoned so it does not slow down anything.

I hope I've helped.
