Okay, if it's two sequential things then it's even clearer that it's not a Feast on second play.
I don't see this at all. It seems like a really moot thing to be arguing; I am saying it's "now Feast twice" and you are saying it's "now Feast and simultaneously Feast." In the second case we need a timing rule and in the first we don't, otherwise they are the same.
I don't understand most of that. If it's two sequential things, then it's "play it, then play it again". The second one isn't even triggered until after we have fully resolved the first one. And what I am saying is that it is
not Feast, it's just "the card you chose". If you think I'm saying it's Feast, then it's clear you don't understand my reasoning.
I'd really wish you'd reply to what I'm concretely saying, such as this:
A) A card gives you an instruction when you play it.
B) That instruction then triggers, but isn't necessarily resolved. For instance Witch: Each other player gains a Curse. Let's say there are three other players. Whether this is three gaining effects at once, or three after each other, they have to be
resolved after each other. If it's three gaining effects at once, all three effects are triggered before either one of them are resolved.
C) "Play it twice" triggers two play-card effects.
D) Either both effects are triggered at once, so that it means "play it twice, simultaneously", or one is triggered now and the other one is triggered after, so that it means "play it, then play it again". A third way of looking at it (although it seems wrong to me), since you compared to Merchant Ship, is that the second effect is now set up to happen after the first one. In that case it would be the same, the second one is triggered then resolved, after the first one is resolved.
E) In either case, the two effects have to be
resolved sequentially.
F) Similar to how Tradering a Copper to a Silver can only happen when you try to gain the Copper, BoM's ability itself can't be triggered until you try to play the BoM.
G) You try to play the chosen card (the BoM) with Throne Room when the play-card effect is
resolved, not when it's triggered.
H) Therefore,
the BoM is not played as a Feast (in fact it's not a Feast) until you try to play the card. No matter what kind of timing we use, the second play-the-chosen-card happens after you have fully resolved the first.You seem to be saying that even if Throne Room triggers one play-card now and one set up for later, it somehow knows that it's a Feast it's supposed to play. But at that point, when "setting up" (i.e. triggering) the effects, we haven't even chosen the Feast yet, because we haven't actually tried to play the card yet.
