Zixor OTK spell hunter (wild)

Should largely play like a typical spell hunter, but with the following OTK if needed:

1. Use Master’s Call to draw the three beasts.
2. Play Zixor, Apex Predator.  Once he has died, draw the prime with Scavenger’s ingenuity.
3. Use Scarlet Webweaver to discount either remaining beast.
4. Play Tundra Rhino and Zixor Prime for a 30-damage finisher.

The remaining card choices are unlikely to be optimal, so if you have any suggestions for improvements, feel free to to comment below!
