Incorrect handling of Flashback when card is exiled

[Ghost-stack]

The bug comes out when try to play card from exile that has alternative cost / other cost. The bug I report
refers specifically to those card that has Flashback as alternative cost. It seems that when you want to play a card from exile that has a Flashback cost, this alternative cost, prevail on the normal cost of the card and you cannot play it unless you play it for its Flashback cost.

To reproduce the bug you have just to exile a card that has alternative cost.
My example is

1. play "Blazing Crescendo"
2. the card you exile is "Dreams of Laguna"
3. try to play it and you are force to pay 3B (Flashback cost), instead of 1B (normal cost)

The expected behavior is allow to play "Dreams of Laguna" for its normal cost
