Thanks for the tips. Although respecting the challenge I don't have the money for Stormbringer just yet. I guess I can rent it but it seems like a lot to track the renting money.

One plan of mine as of now is to one-shot the Air Elemental with Sand Worm, but sometimes it needs two shots due to the summoner's +1 armor. The Wizard of Eastwood + Goblin Thief + Sand Worm is a sure one-shot(assuming the two hits connect) no matter if the armor buff goes first or second. If my WoE debuffs goes first, the elemental will have 1 armor, then my Thief can cut it for the Worm to hit for the 5. This plan only works for high mana matches though. I will look into Coral Wraith and etc and try to find a low or mid mana plan.
