How to deal with the drill mech?

I use the same basic strat as with Gremilion. Range units. For the Driller I found Evil Beholders did very good damage. Cyclops very good. Druids and Demonologist for the range attack and summoned help. Arch-Mage for range and shield if needed. I haven't tried cannoneers but I bet they work well.

Driller and Gremilion both have some sort of range attack but they just didn't use it that much on me, really just 1 time. I had summoned melee units on them as well. It may be there is some programming that has them attack you using range more so when you have all range units and no melee.

Using range and summons like that Driller was super easy. I didn't wait that long so I wasn't over powered up when I went back either.
