In s case where you’ve got an experienced player using a deck they’re familiar with, yes turn 1 can & should be quick. But there are lots of cases where that shifts: new players need to read the cards in their hand turn 1, just to see what they do. So might an experienced player drafting an unfamiliar set, or running a new deck that they copied off a list. The other day I took 10-15s to think on turn 1 when my opponent dropped a Mobilized District as their first land (Are they really on a Colorless deck? What’s that list likely to be? What’s my plan against that? etc). And the risks of shortening the time here are harsh; getting auto-passed through turn one and missing your land drop (or getting flustered and playing the wrong land) is a huge setback for the player.

I get that players that tank forever to decide to drop a Mountain are annoying, and I’m not giving up on finding a way to help that, but there’s a lot of splash damage to consider here.

The most common reason for delayed responses like this is that your opponent is still loading in. Once you’re paired, we let whomever loads first into the game, possibly before the other player has. So if there’s a delay here it’s most likely that they’re still loading rather than alt-tabbed.
