どうも混乱してきたので質問いたします。

「フラッシュバックは自己置換ではない」というＪｅｆｆＪｏｒｄａｎ氏のコメントを見ました。
では、バイバックは自己置換でしょうか、それともただの置換なのでしょうか？

Subject: Flashback vs Memory Lapse Explained

Several people expressed doubts about this interaction. Let me assure
you that it works just fine, as stated in the FAQ. The following
explanation is going to cover two contingencies, then explain that one
of those isn't even possible (even though it still would work as the
FAQ says if it were possible), and finally what would have to happen
for it to not work. So don't get confused by all those hypotheticals.

The simple answer is that Memory Lapse replaces "go to grave" with "go
to library," while Flashback replaces "go anywhere from the stack"
with "remove from play." So it doesn't matter which is applied first;
Flashback will win.

Case 1: Flashback is applied first. The event is now "remove card from
the game." Since Memory Lapse is looking for the event "go to grave,"
not "remove from game," it no longer applies to this event. Result:
Only Flashback is applied, and the card is removed from the game.

Case 2: Memory Lapse is applied first. The event is now "put card in
library." But Flashback still applies to this event, since it is going
to the library from the stack. Result: Both are applied, in the order
Memory Lapse then Flashback, and the card is removed from the game.

But, case 1 can't happen anyway. Memory Lapse is a self-replacement.
You don't have the choice of which to apply first. Flashback is not
a self-replacement - it is not *creating* the event it is replacing.
This isn't an important point, because Flashback "wins" anyway/

For it to fail, there would have to be another replacement that watches
for the card to "go anywhere from the stack" and replace it. There are
none of these (not even Buyback, which only applies to a resolving
spell, and only to a "put in grave" event),

Jeff.
