I'm playing a couple of 2v4 games against the AI at the moment. I thought it'd be useful to note down the obvious AI mistakes and exploits as we come across them.
Tangle Vine can be used as a decoy - We were playing on Mana Piscine, I laid down Vine early on the game, and then we both went in the opposite direction around the map, the AI concentrated far too much on chopping down the Vines, to the extent that it's wizards weren't actually being backed up their creatures.
The AI isn't recognising wizards within Magic Wood as a threat. One just wandered into bolt range as, we think, it only saw the tree and not the wizard in it. Should the AI look at Woods in the same way it sees mounts?
