I dont know, what you all have against Jester...
Of course it is no Witch or Mountebank, but this is not an argument against Jester!
It sorta is! I mean, I'm not saying that it's a bad card. But there are a lot of better options at 5, and well, that's what it gets compared to. It's probably somewhere near the middle of the pack as a 5, I think.
Most common scenarios in beginning : hitting coppers/estate=strong attack, hitting there action card=very strong (at least against reasonable players).
Yeah, but the problem is, you hit an estate means they skip an estate = good for them. Of course giving them a curse is pretty good, so it's overall net good as an attack, but not great. Giving them coppers means them skipping coppers, which is overall pretty neutral. Hitting their actions is of course pretty darn good on most actions, but not all (like chapel - doesn't do much). Probably best early is to hit whatever the best card they have is.
In midgame you give them silvers etc. We all know, that silver clogs their deck.
Okay, I guess here is as good a place as any to bring this up. "We all know this," but in the majority of decks, pretty good majority of decks actually, I just don't buy this.
I would also say to get a own Jester, cards like Moat are not very useful...
Of course this is true, but this is what I meant by "ignore it" - play your own game, just get the best cards you think will help your deck, and if Jester is that at 5, get a Jester. Don't specifically try to counter it, just play your game.
I'm not trying to pick on you at all, by the way. You bring up good points, which is why I'm responding to you while fleshing out my argument.
Also, I think Tydude is right that it's a card (like thief for instance) that gets much better the more players there are.
