Good News for Split Cards

[ShawnieBoy]

The main hurdle for implementing split cards was their multi-information while not on the stack - thankfully Amonkhet rules updates have now removed this!

The core of the change is that we're no longer assuming split cards have two sets of characteristics when they're not on the stack. Some characteristics have multiple pieces of information very naturally—Destined // Lead is an instant sorcery, the same as Ornithopter is an artifact creature. It's black and green just like Winding Constrictor because its mana cost has B and G in it. Continuing that, the mana cost combines the components, and a card asking for Destined to Lead's mana cost sees 4BG.

So now, the converted mana cost question is simple: if Destined // Lead isn't on the stack, it has a converted mana cost of 6. Destined on the stack is still a black instant with a converted mana cost of 2, and Lead on the stack is still a green sorcery with a converted mana cost of 4, but Destined // Lead, any time it's not one or the other, is a black and green instant sorcery with a converted mana cost of 6.

We're aware that this puts a halt to a handful of decks that relied on taking advantage of split card converted mana cost interactions.

Kari Zev's Expertise won't let you cast Breaking // Entering or Beck // Call.
Violent Outburst can't cascade into Boom // Bust.
Isochron Scepter can't imprint Far // Away or Bound // Determined.
Counterbalance revealing Wear // Tear counters a spell with converted mana cost 3, but not 1 or 2.
