Imbalanced when combined with Nap!
On a more serious note, I think it'd be a good idea to get some more creature-synergy. There aren't that many creatures that really enhance eachothers strengths. Schrödinger's cats buff Condor's indirectly and there are probably more examples of indirect buffing.
Direct stat boosts with certain creature combinations like this card would be original and fun
I'm not looking forward seeing these in a fractal/phoenix deck though!
