How does cascade work with split cards

This applies to all split cards, not just the aftermath cards. This rewarded players who dug into the rules and figured that out, but it baffled a lot of players, too. We've had this in the back of our minds for a while as something to fix—split cards are strange.

Their weirder interactions are fun if you understand them, but you must explain them every time you play against someone for the first time, and your opponent never quite believes you at first.

Judges have a long and storied history of trying sometimes in vain to explain split cards to players. Until today, cascading with a card like Violent Outburst would see the front side of an MDFC that cost less than Violent Outburst —say, Valki, God of Lies —exile it, and allow players to cast that exiled card. Then, when casting the MDFC from exile, players would be able to choose which side of the card they wanted to cast—front or back, no matter what the mana cost of the back side was—just like in any other scenario where a player was choosing to cast an MDFC.

The most common way for players to abuse this rules interaction was to cascade into the two-mana MDFC Valki, God of Lies and then choose to cast its back side, the seven-mana Planeswalker Tibalt, Cosmic Impostor. But Wizards has seen enough trickery from the Cosmic Imposter and is changing the rules for cascade to prevent further shenanigans. Cascade is a triggered ability that functions only while the spell with cascade is on the stack. Yo, What happens when I cast a ardent plea and cascade into a split card like beck and call with fuse or development and research?

Is there a difference? Do I stll get to chose the split cost of two mana to play the spell of the higher cost? RE: Cascade-Split cards. Quoting Deathstar Inc: Yo, What happens when I cast a ardent plea and cascade into a split card like beck and call or development and research?

May I chose the split cost of two to play the spell of the higher cost? Anyway: quote from Rules Cascade You may cast that card without paying its mana cost. Then put all cards exiled this way that weren't cast on the bottom of your library in a random order. Split Cards Split cards have two card faces on a single card.

In every zone except the stack, split cards have two sets of characteristics and two converted mana costs. As long as a split card is a spell on the stack, only the characteristics of the half being cast exist. The other half's characteristics are treated as though they didn't exist. Only the half that is being cast is considered to be put onto the stack. Only that half is evaluated to see if it can be cast.
