There's no difference between facing a stacked minion this turn or next, but a fairly large difference (especially when that minion costs 4+ twilight) between your opponent having a minion out for free or paying its cost again. Unless the Shadow player gains more from playing the minion than from having it in play (
When you play... effects, refreshed vitality against archery, etc.), you can get manage a double easier when the Shadow player clears the table on your behalf. It isn't as ideal as simply discarding all minions, of course, but that's the point of
Goblin Swarms. At least, that's been my experience in moving - I've been wrong before!
