Thank you gentlemen.
The rush would be a good option, but he had that lot up in 3-4 turns. I had little guys rushing him by then, just to harass whatever he brought out. When he guarded with golems, my critters took out the mana crystals. I was thinking that would reduce his mana and put me ahead as ten points of his summoning would be dead and my critters would still be alive as 'blocks' or 'guard bait' later. Cervere was out and raring to go but was forceheld
Zone aoe would be great, but I wasn't packing many (any). My next move would be the teleport, but if he plays a wizard as I do, he would teleport straight back.
My general plan here would be to ignore everything and focus on Mage with elusive guys, or tele and tangle vine.
Problem is, ignoring the ballista and tower causes me a lot of damage.
