Unexpected Choices - Team Help & Suggestions

Hey!

So I recently pulled for E1 Tribbie and threw 20 pulls out which happened to net MBlade; I'm currently going all-in for Cyrene when she re-runs but I need some suggestions for what to do with MBlade as I feel like I can't currently complete his team.

E2; Bronya

E1; Silver Wolf, Archer, Tribbie, Robin, Ruan Mei

E0; Castorice, Hyacine, Evernight, Sparkle, DHPT, Phainon, Ceredrya, Anaxa, Sunday, MBlade, Welt

*Sigs on Cas, Hyacine, Robin, Sunday; no others, planning on Evernight when she re-runs. Next golden comp spirit will make E2 Robin, and at 300 standard pulls I can pick up another copy of Welt.

Now with the characters above, what can I do for MBlade? Currently I'm running;

- Cas/Ever/T3/Hyacine

- Archer/Sparkle/Robin (Flex)/DHPT

- Anaxa/Ceredrya/Sunday/DHPT

Long-term I want to grab Ashveil which I know would pair well with MBlade and Acheron, but I'm trying to understand how I can best utilise MBlade right now. Really appreciate any suggestions!
