The AI is, in general, quite a bit too trigger happy with non-creatures. It will cast it's winter blast on a single flier if it thinks it can kill it. If it held onto the Winter Blast it could've used it to just win the game a few turns later.

There's a lot of this sort of thing, should I report every individual instance or do we make one ticket where I can just add them? I don't mean to add any removal it's trigger happy, with just when it causes arguably severe missplay/misshandling of particular cards.
