That is a game called Dark War. Used to be fun, I really have no idea what its current state is but it was lots of fun back then.
I'm not your budd, before calling someone dumb you should look upon yourself. I'm going to give you your own advice: Check the rating. https://dochub.com/bmdarkness95/jwyOwN/tg_dw_tier_list?dt=yyDyyza2jEvL3BL2Fcye
I believe your are looking best unit for tp or to farm stimulant, since everything else is pretty much irrelevant, so.:
Assuming full mastered units for TP:
(Limited)
-kaneki (halloween, valentine)
-shiki (halloween)
-Amon (valentine)
-Eto (kakus buy)
-kisho arima (kakus buy)
-masumae (valentine)
-toru dragon (limited)
-toru (new year)
-urie (new year)
(NON Limited)
-juzo candy (clown coins)
-uta mask (clown coins)
-arima (clown coins)
-urie
-toru
To farm stimulant, you need Time Cut units to bring down the timer since you need faster runs (full mastered). Here look for a column called "Time Cut" or "Time Cut (No Mastery)" and sorted (9→1).
Check this table to see top tier dispatch unit (100% mastery or not) to obtain TP, specifically the TPpM (Territory Point per Minutes) column.
