Rags // Riches

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

Once Riches begins to resolve, no player may take other actions until it's done. Notably, opponents can't try to remove a creature after choosing it but before you gain control of it.

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.

Rags affects only creatures on the battlefield at the time it resolves. It won't affect creatures that enter the battlefield or noncreature permanents that become creatures later in the turn.

Riches's effect doesn't target. Creatures with hexproof may be lured away this way.

In a multiplayer game, if a player leaves the game, all cards that player owns leave as well, and any effects that give the player control of permanents immediately end.

A spell with aftermath cast from a graveyard will always be exiled afterward, whether it resolves, it's countered, or it leaves the stack in some other way.

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

If another effect allows you to cast a split card with aftermath from any zone other than a graveyard, you can't cast the half with aftermath.

While not on the stack, the characteristics of a split card are the combination of its two halves. For example, Destined // Lead is a green and black card, it is both an instant card and a sorcery card, and its mana value is 6. This means that if an effect allows you to cast a card with mana value 2 from your hand, you can't cast Destined. This is a change from the previous rules for split cards.

If you cast the first half of a split card with aftermath during your turn, you'll have priority immediately after it resolves. You can cast the half with aftermath from your graveyard before any player can take any other action if it's legal for you to do so.
