Freeze the trons when you need them and Polymorph or Destroy the trons with your spells when you want to get rid of them. Grim Patrons and Gurubashi Berserkers are nice to have around if Toxitron stays alive for a few turns.
This deck is also useful against Atramedes as you can freeze him so that he can't use his weapon. I let my Water Elemental freeze him several turns in a row while I controlled the board with my spells. That was enough to finish him.
