Friend Invite Bonus Cards

[faerylove]

I am new to this game and I do not have any friends that play online games but I am wanting to obtain the friend invite bonus cards. Does anyone have any suggestions on how I might be able to do this? All suggestions are appreciated. Thanks.

Force family members or rl friends.
Or just spam your id in play store/app store comments.

At lower levels, first reward is awesome. The second one isn't but has an interesting skill. Never got the third one but it should be awesome at higher levels too. (Can someone confirm this? Just a speculation seeing skills and base stats plus, she has 60 levels so I guess stats will go hiiigh)

Imo the last two rewards arent any good, succubus was easily obtainable during the panzer dragon quests and u can still get her by doing ordinary quests. Wouldnt bother too much and focus on getting decent cards from ur guildshop...

Thank you both very much for your comments. They have been very helpful.
