Does Blood Rush repeat make you draw twice for Jae Medarda?

Yes, playing Blood Rush with the Repeat cost allows you to draw twice for Jae Medarda.

According to RiftJudge FAQ #10385, this works because:

1. Jae Medarda's Ability: Her ability, "When you choose me with a spell, draw 1," triggers whenever she is targeted by a spell.
2. Repeat Mechanics: The Repeat keyword allows you to execute the effect of a spell one additional time. When you use it, you are choosing your target for the initial effect, and then choosing your target again for the repeated effect.
3. Two Triggers: Because you are choosing Jae Medarda as a target twice, her ability triggers separately for each instance.
   • First Trigger: You draw 1 card.
   • Second Trigger: You draw 1 card.

This is consistent with Rule 355.14.d, which states that each target chosen contributes to triggered abilities individually. Since your Repeat allows you to execute the effect and choose the target a second time, you satisfy Jae Medarda's trigger condition twice.
