~~MTG:Online INFORMATION~~Sadly, Hive Mind and Eternal Dominion is a faulty combo. When Eternal Dominion goes on the stack, the Hive Mind effect resolves, making a duplicate spell controlled by your opponent, but with the same target: himself. He is not required to change the target, resulting in the spell being countered due to not having any legal targets (he is not his own opponent, according to wording on Eternal Dominion).
