Creature â Human Knight
Hexproof from black (This creature can't be the target of black spells or abilities your opponents control.)
Knight of Grace gets +1/+0 as long as any player controls a black permanent.
Knight of Grace only gets +1/+0 if any player controls a black permanent, no matter how many black permanents players control.
If an effect says that a creature loses hexproof or can be targeted as though it didnâ€™t have hexproof, this applies to hexproof from black as well.
â€œHexproof from [quality]â€ is a variant of the hexproof ability. â€œHexproof from blackâ€ means â€œThis permanent canâ€™t be the target of black spells your opponents control or abilities of black sources your opponents control.â€
