Liquimetal Coating can't be built around properly because the AI will prioritize playing almost anything over it. If one is in play, it will get used properly, but getting one into play is impossible as long as the AI has anything at all it could play instead.

What happens is that if it has 2 mana and the coating and anything that costs 2 mana it will play that instead. Then next turn, if it has anything that it could cast it will cast that. It will cast Uktabi Orangutan with no artifacts in play before it would cast Liquimetal Plating if it had to choose. Then at four mana - same thing, then at 5 mana it will cast 3 Indrik Stomphowler with no targets before it would cast Liquimetal Coating.

This makes a deck which effectively runs 20-or-so Vindicates, and can also destroy all your lands effortlessly, into a deck which runs a lot of vanilla creatures and doesn't work at all.

Can something be done about this? If that card is in a deck it should be very high priority, the AI knows what to do with it once it's in play, too.

The problem, too, is that the AI is way too eager to cast Uktabi Orangutan (and probably similar cards) when there's no targets for their abilities.
