But @yabapmatt told in the potcast to the SEED/Germinator-Promotion that he is the only summoner except the water summoner who add +1 magic buff. The question is if this announcement was correct, because when you could reedeem your Tron token Archmage was already released.
So to the time of this interview their was no other summoner, but it was no time when the card was the only summoner with magic attack, as Archmage was able to play before Delwyn.

I think it is really not a good way to deal with investors - also if I think that the game is great I feel that they do not good by dealing in this way with the investors from SEED/Germinator campaign.

So in the end 75.2% of their cards (this the drop rate for common cards) are now nearly worthless cause they bring first Archmage and later reduce his mana cost - this is the point.

If they really think about their investors and honour that they take part they should in my opinion reduce the mana cost from Delwyn, so that this investment make sense.
