Here, I think you could afford to save the mana so that you could either use the witch in the end step or counter a new dude. As it were, you left yourself open to the 2 new guys which significantly worsened your position. It ight seem a bit greedy but I think it is the correct play since it removes a threat as well as provide you with chumpers to the ghastbark.
