Thanks for your comment 😀

I have collected the UNTAMED cards so that I can use all the cards in the duels without problems. So I don't get any deductions by missing but playable cards.
But I have already reached the goal.

Currently I would like to collect all summoners of RW, because I believe that these can support me in Brawls of the guild.
I have noticed that I use DICE summoners sporadically and do not own all of them.
I simply want to prevent this.

In a sense I do both, I build a deck and I am also a collector 😄
