So, my playmat will not work

I was going to have a playmat embroidered of [[The Tabernacle at Pendrell Vale]]. It would have measured approximately 20 inches wide, and 16 inches tall. Turns out it would take 6 hoops, which are nigh impossible to line up, and 32 hours of stitching.

So, my new project is to do smaller artworks sewn together to make a playmat. The question is, which 6 artworks to choose?

Clearly the Tabernacle will be one. [[Jace, the Mindsculptor]] will be another. Do I do the Gatewatch with the Tabernacle? Or do I just do iconic cards? Those would include [[Tarmogoyf]], [[Lightning Bolt]] and so on.

Help me out, Redditors. What would look great as an embroidery? These will be roughly 5 to 7 inches tall, and 6 to 8 inches wide.
