@Jayyyygs Thanks for that. But my blue demon Meliodas is already doing good as AoE unit for farming and Death Matches. Also, I can't farm anymore. I ran out of everything: dungeon keys, gold keys, etc. And I can't buy them using coins or real money.
I want to improve my PvP. I was doing good when PvP was 4v4, winning against opponent with same CC as me. Now it's 3v3 again, I'm doing pretty terribly (using the first 4 above, Meliodas as sub).
Halloween Gowther is slightly better than Red Gowther since it has dissolve. Also one of your merlin's so it can help associate escanor and demon meli. Also if you upgrade Weinheidt he'll be pretty viable when farming.
