I mean the owner needs to discard a gravekeeper card to keep it from being destroyed. You just need to make sure you can keep on attacking it. Plus, the owner will still take battle damage. So, essentially keep on attacking it. Or see if you can take control of it.
Hey Guys ... Here is the ultimate solution for This scaring monster ... its ATK may reach 5000 ...
The solution in my opinion is "Champion's Vigilance" ... The idea here is that you negate the summon then I am sure by 100 % that it will be destroyed ... I was playing with Blue Eyes white Dragon and she put Gravekeeper's Visionary and she was having multiple cards in her hand ... Hope Helps
