For Billowing Smoke, since prize cards are discarded when the Pokemon it's attached to gets KO'd, how does this interact with Dubwool V's "Revenge Blast" attack that "does 30 more damage for each Prize card your opponent has taken"?
Revenge Blast does not count any prizes that were discarded due to Billowing Smoke.

How does Billowing Smoke work with Greedy Dice or Jirachi {*} and its "Wish Upon a Star" Ability?
If you KO a Pokemon with Billowing Smoke attached, you do not get to use Greedy Dice nor Wish Upon a Star since neither of those cards would be going into your hand. Any Prize cards that would be taken for a Pokemon that has Billowing Smoke attached are discarded, not taken.
