Zinnia, Valley's Voice (Borderless) (4) [Bloomburrow Commander]

Flying Zinnia gets +X/+0, where X is the number of other creatures you control with base power 1. Creature spells you cast have offspring {2}. (You may pay an additional {2} as you cast a creature spell. If you do, when that creature enters, create a 1/1 token copy of it.)
