I've always thought it would be kinda cool to have a Myth morph, but here's my best guess at why they don't have one. Myth's specialty is summoning monsters and changing they way combat works. Turning into a monster to summon more monsters would be a little odd. Plus, summoning a minion as the polymorph creature and then summoning your own minions would pose a problem. I'm not even sure if a myth polymorph would have minion spells, but this is my best guess.
Like the title says, why no myth polymorph?? there is one of all the other schools but none for myth?? Is there any plans to change this?

Eventually, I hope, there will be a myth polymorph. Maybe it's one of those new spells coming with the Wintertusk patch. You just have to keep a watchful eye on those trainers.
