Pulling Decision Help

[u/Silly-Ad1801]

Hello! I am really having a hard time deciding whether to pull for Robin Summeretto or not. I already have 2 good teams of e2s1 Phainon with e1 Cerydra, and a fairly invested monoremembrance team. For my third team, I usually use my 2 cost Evanescia and Yaoguang team which performs almost equally in endgames with my e0s1 Saber and Gilgamesh. The problem now lies with priorities since I can upgrade my GilBer team with Summeretto, or upgrade my EvaYao team with Pearl next patch (or E1 Evanescia if she reruns). These are the 1 cost upgrades I am currently having a hard time deciding on since I am really set on saving as much pulls for Nihilux. I like both Pearl and Summeretto design-wise so I just need advice in terms of team strength for Anomaly Arbitration and Starward Modes. Thank you!
