Continue building Scarlita (S), Talene (Legendary) or start building Phaestro (Epic) or Reinier (Epic)?

Okay so I don't know what to do lol please help. I have Scarlita at Supreme but she requires another 4 copies to get to Supreme+. I have Talene at Legendary and Phaestro and Reinier at Epic. What's the best move here?
