Brain Explodes

My head hurts right now. On one hand, it's because I have a final exam in three days. On the other hand, it's due to the number of times Necrovalley has been errata'd. The funny thing is that it's only in its fifth errata that the text matches what the OCG rulings for the card imply.

Original Lore: PGD-084: As long as this card remains face-up on the field, all effects of Magic, Trap, and/or Effect Monster Cards that involve Graveyards are negated and neither player can remove cards in the Graveyards from play. In addition, increase the ATK and DEF of all monsters that includes "Gravekeeper's" in their card name by 500 points. 

1st Errata Lore: DL3-001: As long as this card remains face-up on the field, all effects of Spell, Trap, and/or Effect Monster Cards that involve Graveyards are negated and neither player can remove cards in the Graveyards from play. In addition, increase the ATK and DEF of all monsters that includes "Gravekeeper's" in their card name by 500 points. 

2nd Errata Lore: DR1-EN032: As long as this card remains on the field, negate the effects of Spell, Trap, and Monster Cards that affect a card(s) in the Graveyard, and neither player can remove cards in the Graveyards from play. Also, as long as this card remains on the field, increase the ATK and DEF of all monsters that include "Gravekeeper's" in their card name by 500 points. 

3rd Errata Lore: CP03-EN020: Negate the effects of Spell, Trap, and Monster Cards that affect a card(s) in the Graveyard. Neither player can remove from play cards in the Graveyard. All "Gravekeeper's" monsters gain 500 ATK and DEF. 

4th Errata Lore: TU02-EN014: Negate the effects of Spells, Traps, and Effect Monsters that target a card(s) in either player's Graveyard. Cards in either player's Graveyard cannot be removed from play. All "Gravekeeper's" monsters gain 500 ATK and DEF. 

5th Errata Lore: SDMA-EN025: All "Gravekeeper's" monsters gain 500 ATK and DEF. Cards in either player's Graveyard cannot be removed from play. Cards in either player's Graveyard cannot be affected by card effects, except for their own effects. 

Why should this particular revision be of any concern you ask? Well, from the way it's phrased you'd no longer be able to revive monsters destroyed by battle with Goyo Guardian. The new text also implies that Colossal Fighter would now be able to use it's revival effect while Necrovalley is in play, provided it targets itself.

I'm still analyzing the judges' responses on this particular errata so should any updates occur I'll be sure to post them here once I get some "concrete" rulings.

Remember players, the game ends with you.
