I'm just making sure I understand what this ruling on the "combo" means, and why it's like that. I'm leaning slightly toward Guess #2, but I thought I ought to make sure.
Let's pretend it's the same set up, Let's also pretend instead of a 4 gold follower, it is a 7 gold follower.
After Supply Outpost reduces its cost by 3, can I then reduce the remaining 4 down to 2?
Guess #1: No, because supply outpost has already attached the card and thus you cannot react to it having no legal target.
Guess #2: Yes, the remaining cost is 4, and shinsei's last hope would reduce it by 2 to a minimum of 1, so you would still have to pay 2 gold. In the previous set up the 4 gold follower was already 1 gold (after Supply Outpost's reduction) it could not have been reduce further from that point, or retroactively (as you cannot react during effects, only after costs and then after effects) to 2 effectively making the folower reduced to 0 gold cost in that example.

Using Supply Outpost, then Shinsei's Last Hope, is fine. Obviously, cost can't go below 1 in that case.
