Dissension Multicolored Split Selection

These split cards are very interesting. Each half represents a guild, and the combined colors are a shard. For Hit // Run, its Jund = Rakdos + Gruul.

For Rise // Fall its Grixis = Dimir + Rakdos

For Pure // Simple its Naya = Gruul + Selesnya.

For Supply // Demand its Bant = Selesnya + Azorious.

Crime and Punishment is not one of the usual Shards, but its Orzhov and Golgari.

And neither is Bound // Determined, which is Golgari and Simic.

Same goes for Research // Development, which is Simic and Izzet.
