Had to put Cyzir second on account of the fact you can see a but tail through the ice. Just preferred how Quanyails' has an ice block tail with no bug tail inside. (I prefer the see the blob in Quanyail's as the lighting of the ice, rather than being obviously a tail)
Also, Quanyail's sharper front fangs pushed it over the edge for me. :)
Just A1 for short. Apparenlty people can't spell Treadshot.
