Korvold, Fae-Cursed King triggers off sacrificing, Harrow sacrifices as an additional cost to casting. The question is if you cast Harrow while Korvold is on the field, which order do they resolve in? I think Korvold's ability would hit the stack in response to casting, therefore resolving Harrow first. The rest of the group believed that Korvold's ability resolved first. I searched Google to no avail, so I thought someone here may have a rule related answer that I could share with the group. Thank you in advance.
When you want to cast a spell, the first thing you do is to put it on the stack, and the last is to pay its total casting cost (there are intermediate steps in some cases, like choosing targets, but they don't apply here). So Harrow is already on the stack by the time you sacrifice the land, so Korvold's trigger is put on the stack above Harrow. Being on the top of the stack, it resolves first.
Thank you, every game I've played people pay costs before adding the card to the stack. Did not know that was the actual order of things and people were short cutting the process.

I'm quite sure they don't pay costs beforehand. What they might actually do in advance is tap some lands, in order to pile up mana in their mana pool.
But the exact order of things rarely matters, especially not when playing over the kitchen counter!
Yet, your group stumbled on such an occurence...
