This scroll is intended to give Growth a reasonable ranged unit without harming its Resource Identity. Sister of the Hawk is meant to aim at big units in the back row, therefore she comes into play with 1 CD less. So the other player has a chance to deal with her. In return for this advantage, the player has to leave her unprotected in the front row. With lobber, she also doesn't attack idols.
Considering all the attack buffs Grows has, it could be possible to change her attack down to 2.
