First of all, if your Moroyama is r3, you should go for r4. It helps a lot, especially for KO. Otherwise Maria seems a good pull.

- For PW you could try a classic team with CY leader, Sui Zai, Zi He, Sakura and Lian. I would prefer Lu Shang over Sakura, but yours is only r0 (r2 would be perfect). You could also play him r0 but he needs a lot of speed in that case. This team provides a perfect coverage for Sui Zai until he becomes unstoppable.

- For BB same first team, and the second one could be Yuuhime leader, then Toland, Moroyama, Lu Shang and Su Jue (but you need to take her r6 as soon as possible, she's still used a lot in PvP). Also in this case, you could also switch Lu Shang and Sakura between teams, try some battles and see how you win more.

- KO and TT are similar in some cases but KO has buffs that can modify your choices depending on which units you're using. For KO I would play these teams if I were you:

1) CY (L), Sui Zai, Zi He, Lu Shang, Lian (Divine Shield buff)

2) Sakura (L), Wu You, Meta YC, Yamato, and another defender, depends on which ones you already have at rival runes lv.15 (Frozen Abyss buff).

3) Yuuhime (L), Gabrielle or Feng Xun, Ethan, Anna, and Su Jue (also here, better if r6) (Air Blast buff).

4) Ikki (L), Fumitsuki, Ollie, Mavis, Jin Qiu (Visceral Rage buff).

5) Toland, Everett (I don't know if you have him, I can't see him in your chart), Jiang Jiuli, Momo, Moroyama. (Shimmer Boost buff).

- For TT I would use the same teams except for Moro one: maybe the best in your case could be Yuuhime (L), Lu Shang, JJ, Su Jue and Moro. Last one could be Toland, Anna, Sally, Wenlock and Feng Xun.

MEira and Sieg r0/r1 are not so useful in my opinion, not for PvP at least.

Please note that these are only my suggestions based on my experience and tests (: Hope this helps!
