1) They 'encourage' more creative deckbuilding by excluding common deck designs. I am not sure if this effect is desirable.
(we both agree it is not ideal since ideally people would sometimes be building decks that mimic non-stackability with stackable cards)
2) When a card is changed it gets rebalanced. Therefore non-stackable cards are rebalanced if they become stackable. This results in the same balance distribution as normal for the designer in question (Zanz). Please tell me if there is any part of this that is confusing because the propagation of this critique is a problem.
3) Even 6 times? I find that doubtful but you are making the claim so I suspect to be proven wrong.
I will also jump over to that thread.
Bringing the discussion here too.
1) I found that effect desirable, because common deck designs when used everytime and repeatingly become predictable and "boring" I dare to say. Using uncommon deck designs are more exciting to deckbuilders who are called to reach the limits of their skills and intelligence. However, I am not sure what you mean with "common deck designs" here, so I am not 100% sure I agree/disagree with you.
2) It has to be rebalanced for sure and because of this I would never be pissed of by a balanced stackable effect. However, if you include a stackable card once in your deck you are going to get 1x of your card cost, but if you include it 6 times you are going to harvest a benefit larget than 6x times of your card cost. On the other hand, in a non-stackable effect you always get what you have paid for.
Tell me, why do I include my stackable card once in a deck and have only a small advantage while having it 6 times gives a super large one? Isn't this bad for deck design too? If non-stackable effects are not effective if included 6 times in a deck, doesn't the same happened for stackable effects where it is not effective if icluded just once in a deck?
3) Yes! Golden Hourglassed are useful even if included 6 times in a 60-card stall. Multiple shields are useful when you encounter PC and the more PC you encounter the more useful your multiple copies of shields are. Also, if you wish to outstall 30-card rush decks, you may play a permanent-only and/or spell-only deck which are slightly fatter than 30-card decks which need 6 copies of an important non-stackable permanent (shields, weapons, Flooding etc.) in order to ensure you will draw one early and you can replace it if the need arises.
