Mirage common. Called “reverse-trips” by some, the idea behind this Mirage cycle was that you got a small effect, but then your opponent basically got one less card draw (since you put the new card on top of what they would have drawn) rather than you getting an extra card draw. The other cards in this four-card cycle would have been Fallow Earth, Memory Lapse, and Painful Memories, but Memory Lapse got moved to fill a slot in Homelands, so Ether Well was created to replace it in Mirage.
