Monster Book Boss Card Costs

Noooo guys.

If you're actually collecting, then NO MATTER WHAT you should be getting full sets of the PQ bosses before doing anything else. That's 25 cards/days.

I'm going for one of each PQ boss, then probably get up to #3 for them all, then #4 for them all, and finally the 5th.

Imo, even though it's nice to have different types, the impossiblity of getting PQ cards over level 100 makes getting medals on all 5 types a much higher priority than getting a fully coloured page.

+5 Snowman cards ?
i dont know if it's good idea because when Elin Forest I will still have monster which i can't get. Is this event back to kms on anniversary?
