Speaking of the legendary bird trio, we did confirm that thier starting frames depending on which ones have been caught previously.
It really should be added to the OP.
Its along the lines of:
Slot 1 = Frame 1
Slot 2 = Frame 6
Slot 3 = Frame 11
The birds start in these slots:
Slot 1 = Moltres
Slot 2 = Zapdos
Slot 3 = Articuno
If you catch one of the birds however...
Caught: Moltres.
New slots:
Slot 1 = Zapdos
Slot 2 = Articuno
Slot 3 =
Caught: Zapdos.
New slots:
Slot 1 = Moltres
Slot 2 = Articuno
Slot 3 =
Caught: Articuno
New slots:
Slot 1 = Moltres
Slot 2 = Zapdos
Slot 3 =
Caught: Moltres, Zapdos.
New slots:
Slot 1 = Articuno
Slot 2 =
Slot 3 =
Caught: Moltres, Articuno
New slots:
Slot 1 = Zapdos
Slot 2 =
Slot 3 =
Caught: Zapdos, Articuno
New slots:
Slot 1 = Moltres
Slot 2 =
Slot 3 =
I believe thats every combination, so for anyone who has tried to get all the birds with RNG, if you can't seem to get your frame, this might be why.
