I think people are seeing GRNDL like people see NEXT Design: “More up-front for worse long-run”. But that’s not really the case. Hoobajoo’s right on the money about it having a massive advantage in terms of opening with 10 credits. It’s like you got to score Hostile Takeover before the game started in exchange for shuffling it back into your deck instead of keeping the point.
In a normal game, BABW might make 9-10 at most, barring Subliminal Messaging. Having it upfront means you can rez Ice and score, or pay for Snares, and just generally begin your first turn launching your econ to higher heights, rather than scrabbling to be able to handle the initial assault.
I can only say so much, because the GRNDL deck I play against most (a Supermodernism variant) doesn’t run any of the cards you’ve mentioned and seems to do pretty well. I can’t claim to be pushing it as hard as a better player might, but even so I gather that in person and on OCTGN it wins a fair bit more than not.
My own experience of playing with GRNDL says it’s waaay better than BABW, but people shy away from the BP in favor of forcing themselves to run event economy. “Oh, but event econ is better anyway” you might say. Not… really? I mean, yes, it is, but running 3xBeanstalk, 3xHedge Fun, and 3xRestructure is still tricky (as Restructure is unplayable first turn without at least one of the other two, at which point… Ice?) and forces you into a particular style of play. Sweeps Week helps that style be even better, sure, but…
Well. You should always try for a hand with econ and Ice both, of course, but GRNDL can start without much more easily. Drawing econ that first turn isn’t as essential – and if you’re not trying to rez all the big, expensive things you can find, then you don’t need to be rolling in money in quite the same way. Which isn’t to say you won’t be, with Restructure first-turn playable, but…
It also cuts out Beanstalk Royalties entirely. Other event econ as well, freeing up deckspace for other things. More useful things.
It’s not like Weyland’s Agendas don’t give all the econ you need once they get rolling.
(I’ll bug the person that runs the deck I play against into sharing his thoughts on it, too.)
