In advance, I understand that the baseline answer is: "It depends on the deck."
I get that, of course.
But, as far as I can tell, it's essentially a Band of Misfits, but able to emulate a 5 card, instead of only a 4 or lower card, right? Some other advantages I am missing?
I almost never have 8 coins in the beginning of a game, although it does happen with the right deck from time-to-time. One hopes there's a King's Court on the table, or another great 6 or 7 card available. But if not, we all would likely buy a Gold, since we don't want to clog our deck early on with green. And at the endgame, we are all buying a Prov almost all the time we have 8 coins. So, we're talking about a fairly narrow midgame range, where buying an Overlord makes sense.
Or, is it especially valuable since it's a Debt card, and can be bought on the very first turn of the game, as opposed to regular cards that require actual coins in hand?
As you more-experienced players have been seeing this card in your games; is it a must-buy most of the time? An almost-never buy most of the time? What sort of decks does it work well with? (Duh; where there are a few great 5 cards
, I'm guessing, right?)
