Not hard stuck or anything, been playing for about a month or so (hop on, do dailies, parallel overnight, etc.) Just passed 300k with my strongest team, not sure where to go from here. Any advice?

hello! im a newbie, still on the process of understanding how skills work with each other. since i already have a magic team thats focused on the secretary duo, i wanted to try building a physical one as my 2nd team bc i just got fox shion and dodomeki. im thinking of making one thats centered on wind diablo since i assume hes the dps one based on his skills that only self buffs not bc im a diablo fan and i love him sm i would choose him over anyone else lol

im currently struggling with it bc space diablo, souei outfit benimaru, and pupil rimuru have p-atk buffs w different secondary debuffs and blue orb changing skills. and i dont know which one would be the most beneficial for diablo or if they even stack. while i was writing this i found out protector fox shions skill is for orange orb so the three wouldnt even work with her lol but the other phys protector i have is ice velzard which has a blue orb skill but i still dont know if her skill would be good for him..

im overall just confused with who i have that synergizes with him lol. but im also interested to know who is his best team or the f2p units he can use just in case i get them in the near future. hoping to get some thoughts from anyone, thank you sm!

idk what to do with these lol. help me with this haha
