Dawn's Truce

In the main set, there are four different kinds of gifts. "Gift a Food" causes the chosen opponent to create a Food token, while "Gift a Treasure" causes the chosen opponent to create a Treasure token. "Gift a card" causes them to draw a card, and "Gift a tapped Fish" causes them to create a tapped 1/1 blue Fish creature token. The Commander decks contain two more kinds of gifts: "Gift an Octopus," which causes the chosen opponent to create an 8/8 blue Octopus creature token, and "Gift an extra turn," which causes them to take an extra turn after the current turn ends.

You can't pay a gift cost more than once.

Some instant or sorcery spells require alternative or additional targets if the gift was promised. You ignore these targeting requirements if the gifts aren't promised for those spells. On the other hand, you can promise a gift for a permanent spell even if you won't be able to choose targets for an enters ability of that permanent once the spell resolves.
