Mogg War Marshall encourages goblins to go wide and gives sacrifice fodder to the BR deck.

Momentary blink is a clear signpost for WU and this archetype is now fairly complete in my eyes.

The buddy lands are classics so I'm glad they're able to be introduced to the enemy colours.

I initially don't think the other spoiled cards benefit the cube's archetypes and I still want to avoid adding new cards that are just generically powerful. In particular, I am avoiding adding any planeswalkers.
