No, that's why I said 'guess'. I don't know how Donald would feel about discussing previous versions of summon here so I won't, but suffice to say I have experimented with weaker versions that I already considered very strong.
And just for clarity: I'm not saying it's a badly designed card at all. First of all it's an event, so it will be available for everyone all game. Secondly it won't make all games look the same (a la rebuild or cultist) because it makes you play with the rest of the kingdom. And finally it's a promo, so nothing wrong with being a bit spicy.
All I'm saying is that I expect to buy this event almost whenever I can. And I expect that whenever I buy this event, I will be able to afford another the next turn.
Uh, it's probably fine if you talk about the previous versions. Man. We know the card. When Adventures was getting previewed and the playtesters were saying what they thought of each card, it felt to me like, aren't people missing some joy of discovery here? But really a lot of people wouldn't see the posts, and a lot of the people who did would see lots of posts in-between when the set came out and they got it. I guess you could spoiler that stuff. You are to some degree spoiling card analysis for the people who will get the card ASAP.
I agree that, if Summon turns out to be in some sense overpowered, it's not so bad. It's the kind of thing that probably won't be hated by very many people; it makes you play more with the cheaper cards but that's not making things boring.
Stef was the one who figured out that the original or maybe 2nd version was crazy. It was $1-$2, buy an action card (so, paying the cost of the card but being able to get more expensive stuff), play it next turn. The current version is trying to be fixed, so that you will in fact not always buy it. I don't know how it will end up for serious players, but I don't see typical players just passing up good $5's constantly.
