Rags // Riches

Once you've started to cast a spell with aftermath from your graveyard, the card is immediately moved to the stack. Opponents can't try to stop the ability by exiling the card with an effect such as that of Crook of Condemnation.

If another effect allows you to cast a split card with aftermath from a graveyard, you may cast either half. If you cast the half that has aftermath, you'll exile the card if it would leave the stack.

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

Riches's effect lasts indefinitely. It doesn't wear off during the cleanup step.

In a multiplayer game, each opponent in turn order chooses a creature they control, if they control any creatures. After each opponent has done so, you gain control of each chosen creature simultaneously.

All split cards have two card faces on a single card, and you put a split card onto the stack with only the half you're casting. The characteristics of the half of the card you didn't cast are ignored while the spell is on the stack. For example, if an effect prevents you from casting green spells, you can cast Destined of Destined // Lead, but not Lead.
