Do you draw from Stellacorn Herder if it gets returned to hand from Star Crossed?

No, you do not draw a card from Stellacorn Herder when it is returned to your hand by Star-Crossed.

Reasoning

1. Recall/Return vs. Move: According to the established rulings for Riftbound (notably RiftJudge FAQ #10159 and #10124), the game distinguishes strictly between a "Move" and other forms of displacement, such as being recalled to your base or returned to your hand.
2. Trigger Condition: Stellacorn Herder’s ability ("When I move, draw 1") triggers only upon a Move action. Being returned to your hand by a spell effect is not considered a "move," so the trigger condition is never met.

As established in RiftJudge FAQ #6601, the unit must actually perform the move action for the ability to trigger. Because returning a unit to its owner's hand is a separate game action, it does not satisfy the requirements for Stellacorn Herder's triggered ability.
