Hi. I was searching for noob question thread but couldnt find one so here it goes:
Recently I've been wondering, is it worth to sell some unused monsters to get MPs? I have some of them which I feel like I won't be using for various reasons, some don't match my playstyle (like Fenrir) or cant find suitable spot in my teams (like Divinegon)

I had in mind two options for spending those points: - Buy 300k monster from MP store, Xiang Mei or You Yu to be exact (although for the first one I have Gadius and Uriel, but one each, so filling rest of the spots can be tricky. For the latter I have Nut, Orochi, Gabriel, normal Urd), OR wait for Shiva Dragon
- Second option would be buying tons of tamadras. Since recently I've obtained some decent subs/leads but I completely lack means of awakening them (cant buy many Tamadra villages from the coin store) and hunting for tamadra invade will take me years to awake them fully, since I need around 60 awakenings (I have lvled but "naked" Awoken: Shiva, Cao Cao, Venus, Freyja, Anubis, and from the rest there are subs Sarasvati Team (2x Sara, Andro, Gabriel, Orochi, Sitri) and few others)

Among notable monsters to sell that I have no use of (I have Fire teams (Urd or Gadius or Cao), Saria) are: Lmeta (have 2), Fenrir, Baldin, Sitri (dupe), DMeta, and some event REM rolls, which would sell total for 100-185k MPs. Although I will still need around 15-20k pts

To summarize aka TL;DR:
- I have REM monsters which I dont plan to use - sell or keep?
- If sell above, what do do with MPs
- Should I buy MP monster, which one, if hoard for something, for what?
- I need shit-ton of tamadras, how to get them fast (other than "farm tamadra invades/village")

Thanks for answering lame questions :D Regards
