I've been wanting to get a hold of "Baby Jace" for some time now, and now that I've got him, I'm taking out Aetherling. More looters are more welcome than additional Morphlings, it would seem. This looter makes three with Merfolk Looter and Thought Courier, and three seems to the sweet spot for my cube. Functional reprints and close variations are good for a cube when you want a more well rounded draft experience while maintaining some variety.
