Um... Gravekeepers don't need anything right now. They've been meta for a while. Anyway, on to the cards. Stone Guardian is just wow. Destroy three cards, and deal 3000 life points of damage as long as a certain card, which this one actually protects, is on the field, and all it needs is DARK monsters, and ones that don't need tributes at that. That sounds broken beyond belief. Something needs to go on that one. I don't think that Mummy Dragon has a problem, it looks like a solid card. Atem... Just no. Combining effects of the already crazy powerful cards like Assailant, Chief, and Descendant. I can see just infinitely broken combos right now. A good start would probably be to change it from DARK monsters to "Gravekeepers", It may not sound like much, but it changes the possibilities from millions to just dozens. I also don't think the ability to Summon Atem from Dunston, is a good idea. Considering the massive amounts of materials it can get, It could get to over 9000 attack and Assailant's power to change a monster into attack mode, dealing thousands of damage in one hit.
