Not sure if it's individual card or duel AI but I've just had the AI do the following:

It had 2 Nephalia Smuggler and 2 Trinket Mage on board, all tapped from attacking. Then it cast Displace... on the 2 Nephalia Smuggler. Wrong on multiple levels.

The biggest is that it didn't prioritize ETB creatures to flicker, which is something od a big problem as most decks with flicker effects will feature them in order to do precisely that (this one did). Can this sort of effect be made to prioritize ETB guys?

Or does the AI just have problems with targeting Trinket Mage with it? I've had a Nephalia Rogue flicker a Faerie Miscreant in order to draw a card instead of flickering a Trinket Mage in order to tutor equipment.
