can you use multiple specials in one defensive action?

[breadmaster]

i'm guessing no, but i thought i'd ask

can you play a training/powercard/special defense (ex.  prof x +2/power card/training card), 

what about a special along with a double shot

finally,  if you have jean grey and prof x, can you play the BG (+2 to all actions) and the BH (team +2 to defense) in the same defensvie action?

First: I would say yes, but the meta rules say no.

Meta #38: Bonuses/abilities granted by Special cards affect Universe cards played on subsequent turns. A Universe card may not be played in conjunction with a Special card unless the Special card or Universe card explicitly say so.

Second: Doubleshots are not universe, so #38 doesn't apply. Then #54 applies:

Meta #54: Specials which grant bonuses/abilities/grid changes may only be played defensively if it is necessary to do so in order to defend.

Third: No, BG/BH can only combine with a single power card.
