King of Filth

Change the text of spells and activated abilities
and triggered abilities you control by replacing all
instances of "your graveyard" with "a graveyard."
If a permanent would enter the battlefield from a
graveyard under an opponent's control, it enters
the battlefield under your control instead.
"At the bottom of the well, the reviled king waited;
his kingdom now vermin, consumed by his hatred."
- Dirge of King Verius, Final Verse
