I am curious what you all have done with this card. So far, my favorite use of the card is using Heaven's Assistance, and next turn use Equilibrium. This ensures that you a) have enough blockers to match the amount of creatures you opponent can attack with the following turn and b) whenever one of your HA angels blocks, it will ensure the attacking creature dies as he only has 1 hp (assuming no Rakarl, etc).
I am using this combo to great success so far, and I find that it really throws people off.
Has anyone else found an actually potent use for this card?
