Graywater's Fixer

If one of the tokens somehow is under another player's control as the delayed triggered ability resolves, you can't sacrifice that token. It remains on the battlefield indefinitely, even if you regain control of it later.

Graywater's Fixer itself doesn't have encore. Its ability applies only while it's on the battlefield.

The tokens copy only what's on the original card. Effects that modified that creature when it was previously on the battlefield won't be copied.

A card, spell, or permanent is an outlaw if it has the Assassin, Mercenary, Pirate, Rogue, or Warlock creature type. It doesn't matter if it has more than one of those creature types; as long as it has at least one, it's an outlaw.

If one of the tokens can't attack for any reason (such as being tapped), then it doesn't attack. If there's a cost associated with having it attack, you aren't forced to pay that cost, so it doesn't have to attack in that case either.

If the mana cost of a card in your graveyard includes {X}, X is 0 for the purpose of determining its mana value.

Opponents who have left the game aren't counted when determining how many tokens to create.

Outlaw is not a creature type. If an effect asks you to choose a creature type, you can't choose outlaw.
