As you are a starting player, Fenrir will likely be the main card/attacker you will be using in your team.

BUT despite it really giving a big boost for your team now and very tempting to, DON'T DO IT. There are so many more cards that are more useful and more powerful than Fenrir. UR Mirror Maiden is not something that comes by often and easily so only reserve using her for the best. :)

If you need help to fight against Archwitch(AW) and Fantasy Archwitch(FAW), I recommend looking for an active alliance in the Alliance Recruitment Boardand join one if you are not already in one. Also, you can add people who are willing to kill them in the Comrad Request Page, look for the killers section and add them. Send your AW and FAW to your alliance and comrads(That are logged on within 1 hour) for them to kill. Meanwhile keep playing and be active in events, at the same time building up your collection and you will get stronger and stronger. :)

I welcome questions, feel free to ask, I'll try my best to answer. :)
