Yeah, I’ve had many problems where this card won’t activate and have lost many games due to this issue. Right when my turn would begin I would try to use this card and the game wouldn’t let me. I’ve email konami many times about this and they only response I’ve got was an automated email saying it’ll take them a couple weeks to email me back. That shows me that they don’t really care.
When your life point is 2000 or lower, this card would be such a big advantage. Savage!
