I didn't play with the three-color creatures headlining the five wedges of KTK at rare:
Siege Rhino Abzan
Butcher of the Horde WBR
Savage Knuckleblade RUG
Mantis Rider WUR
Rakshasa Vizier BUG
I am leaving Siege Rhino for later.
The Rakshasa Vizier deck turned out like other fails I have tried in the past. The best way to improve on the many deck variations I tried is by removing Rakshasa Vizier. Instead of boring you with a bunch of losses, here is the deck as a failed experiment.
