Flotsam // Jetsam

You can't sacrifice a Clue to pay multiple costs. For example, you can't sacrifice a Clue token to activate its own ability and also to activate Alquist Proft, Master Sleuth's ability.

Each split card is a single card. For example, if you discard a split card, you've discarded one card, not two. If an effect counts the number of instant and sorcery cards in your graveyard, Cease // Desist counts once, not twice.

Each split card has two names. If an effect instructs you to choose a card name, you may choose one of those names, but not both.

To cast a split card, choose one of its halves to cast. There's no way to cast both halves of any of the split cards featured in this set.

If you cast a spell "without paying its mana cost", you can't choose to cast it for any alternative costs. You can, however, pay additional costs, such as kicker costs. If the card has any mandatory additional costs, those must be paid to cast the spell.

A split card's characteristics are a combination of its two halves while it is not on the stack. For example, Cease // Desist has a mana value of 8 while it is in your library. If an effect allows you to search your library for a card with mana value 4 or less, you can't find Cease // Desist.
