Boost Shake says it can be used during my first turn or on a Pokemon that was put into play this turn. What if my Basic Pokemon was in play last turn but I evolve it into a Stage 1 this turn; can I use Boost Shake on that Pokemon to search for a Stage 2 and put it onto that Pokemon?
Yes, you can.

If I have Milotic with the "Dew Guard" Ability in play and my opponent plays Avery, do I have to discard Pokemon from my bench until I have 3 or not?
Milotic's Dew Guard prevents all effects of your opponent's Supporters that are done to you, so you would not discard any Pokemon from your bench for the second part of Avery.

Can I use Raihan if I don't have any basic Energy cards in my discard pile to attach to 1 of my Pokemon?
No, the main effect of Raihan is attaching a basic Energy card from your discard pile to 1 of your Pokemon, so you can't play the card if you can't do that.

If I have four Plasma Energy in play, either on the field and/or in the Discard Pile, can I use Colress Machine to search through my deck, find nothing, and shuffle my deck?
No you cannot. Since the location of all four Plasma Energy cards are known, there's no way Colress Machine would be able to find one during a deck search.

If I attacked with a Rapid Strike Pokemon last turn, then use Ninja Boy to swap it with Zeraora V, would the Zeraora V's "Cross Fist" attack do damage to a Benched Pokemon?
No, all effects carry over, so it would be considered the same Pokemon.
