I also think that nerfing cards is going to be bad to FG killer decks, but also very bad to all other decks. And my point is, why is zanz doing that? A card like Steal is very very used and a card like Stone Skin is almost not used. Why? The answer is the cards costs? Of course its not, most important is the card effect.
He buffs Stone Skin to a cost of 1 when upgraded, but its a silly effort. Having a great amount of
is not the point of any deck, and in fact, it will hardly gives you the victory.
At other hand, how many times you have lost due to opponent shield / weapon? And the single non-rare cards that have low costs and can handle with enemy shield / weapon are steal and deflagration. Im sure that most decks that use darkness use steal, because its difficult having a better way to control enemy permanents. And its strange Steal is very used? Of course its still used in rainbow decks, and because of this, even more used. Increasing its cost by 1 will make it less used? Maybe a little bit, but will still be very used, because its effect is simply great.
So, if zanz idea is to make all cards used at same amounts (and it seems that its his goal, because hes nerfing used cards and buffing almost non used cards), he will get an epic fail, because the cards effects will determine that. So whats the point?
If a card is not being used, maybe its good having a buff, but its not necessary. This game is still on beggining, and surely will get tons of new cards, when maybe a forgotten card can become the key at a popular deck (looks like Hope can do that to Luciferin).
If a card is being used, its a good card, it has a good effect, just this. Nerfing all used cards is not necessary, nor welcome. In fact, FG should thank zanz a lot after an upgrade like this, when he makes worse our little tools to beat then. Because we need to get that stupid electrum hourglass and pay to have a card advantage they have by start, for example, and now its more difficult. And we need cards like Steal to have a chance against like 20 gods different strategies, but its also harder now.
Guys, every card game needs powerfull cards. If a card is powerfull, make it harder to get, like the rare cards in the M:tG packs. I dont think almost all cards shouldnt be available in bazaar, but how about higher prices for the good ones? Dragons are usually most expensive ones, and have low use. Maybe remove the most used cards from the spins. What do you think?
