Blackpool stand on the brink of a return to the top flight for the first time since 1971 after a DJ Campbell hat-trick helped sink Nottingham Forest 4-3 on the night and 6-4 on aggregate in a Coca-Cola Championship play-off semi-final that swung one way then the other at the City Ground.
Leading 2-1 from the first leg on Saturday, Blackpool fell behind on the night to Rob Earnshaw's early goal.
Campbell equalised at the start of the second half before Earnshaw scored his second goal of the game to level up the tie on aggregate at 3-3.
Substitute Stephen Dobbie then made an immediate impact with his deflected shot wrong-footing Lee Camp and trickling into the net before two quickfire goals from Campbell sent Blackpool to the Wembley on May 22.
The Seasiders' hero will be ineligible for the showpiece if his parent club Leicester overcome Cardiff in the other semi-final.
Forest substitute Dele Adebola scored in injury time to make it 4-3 on the night but it was mere consolation for the hosts.
