Well, until they come up with a card stealing mechanism then I don’t see how it hurts the non-rush player. If I don’t have any scoops to destroy then using a card against me is useless. Quick example:

player 1 – 25 scoops 5 cards

player 2 – 5 scoops 10 cards

player 3 – 8 scoops 10 cards

player 4 – 0 scoops 5 cards

player 5 – 0 scoops 10 cards

So player 4 and 5 can bumhole player 1 but player 2 and 3 cannot. Players 1,2,3,4,5 can steal each others scoops or play shotgun cards but still can do nothing to the player with no scoops. Let’s say everybody is reduced to zero scoops and the new board looks like this:

player 1 – 0 scoops 3 cards

player 2 – 0 scoops 5 cards

player 3 – 0 scoops 6 cards

player 4 – 0 scoops 2 cards

player 5 – 0 scoops 8 cards

So clearly now player 5 is in the best position to win since they have the most cards but since everybody is at zero scoops card timing becomes a factor because the next player to use a modest improvement has four other players that can attack them.
