Hidetsugu never relinquished a grudge. He let it burn within him, gathering ever greater intensity until the final moment of vengeance.

Hidetsugu's Second Rite

If target player has exactly 10 life, Hidetsugu's Second Rite deals 10 damage to that player.

Once a mortal ogre, Hidetsugu devoured his demonic patron and transcended mortality in a fit of rage.

The List

Historic Anthology 1

Saviors of Kamigawa

Since the player's life total is checked only as the spell resolves, you can cast Hidetsugu's Second Rite targeting any player, regardless of life total. If the player isn't at 10 life as Hidetsugu's Second Rite begins resolving, it does nothing and finishes resolving. Note that since having 10 life is not a targeting restriction, the spell isn't removed from the stack for having an illegal target; it just won't do anything.
