It been going on for quite awhile now (since KLD release). I have notice Ai casting Giant Spectacle (red common) on my creatures instead of it own. I do get that there is strategy behind it. But i highly doubt the Ai is that clever. Since it uses Skywhaler’s Shot(uncommon white removal from KLD) on its own creatures.
I remember when SoI first came out the AI would use damage spells on it own creatures and buff spells on mine.
Should look into it Devs.
Have a nice day.
