Personally I don't believe you need any summon cards to be competitive in this game. Although most of the good looking ones are from summon. For players who are card collectors, I'm not sure how they feel about dishing out so much money for them. I mean you could probably get some cute figurines for a fraction of the price.

As for the indirect price hike, this may have a negative effect on the game especially when it depends on the revenue from whales. You may be able to extract more money with this scheme but at the same time less people will be willing to throw money I would assume.
