[LOLZ]

Accelgor uses Deck and Cover, opponent has Virizion in play and defending Pokemon has G energy attached.

In this case:
The 50 damage is done.
Accelgor attempts to place the Special Conditions of Poisoned and Asleep.
At this point, Wobuffett is still on the bench, so Verdant Wind blocks those Special Conditions and they are not placed.

Accelgor (and attached) is now shuffled into the deck. Wobuffett is brought up as Active.
KO's are checked for. Assuming that the 50 damage is not enough for a KO, the turn ends and it is now the other players turn.
Their Pokemon has taken 50 damage and that's it. No Special Conditions are on it.
