I lump 6+ drops together for green. So this would have to compete with primeval titan, hornet queen, terastodon, woodfall primus, etc. And compared to those this just won't cut it.
I recently took it out of my Cube, never really saw play and to be honest it went in because I killed with it a few times in limited/sealed/draft etc but the setup to actually make it profitable wasn't worth it mostly. Classifying it under the 6+ drops overall is probably a good idea and it doesn't really stack up but no one will fault you for trying.
Anyone played See the Unwritten in cube? At what size? Did it perform well?
The floor on this card is too low.
