If my opponent uses Mime Jr's "Mimed Games" attack and they don't have enough cards in the Lost Zone, can I choose Sableye's "Lost Mine" attack and if so what happens?
No, you may not choose that attack, you must select a different attack.

If my opponent uses Mime Jr's "Mimed Games" attack and I also have a Mime Jr. in play, can I choose my "Mimed Games" attack, and if so what happens next?
No, you may not select Mimed Games if your opponent attacks with Mimed Games; you must select a different attack. And if your only Pokemon in play is Mime Jr., then your opponent's Mimed Games won't do anything.

If I receive cards in a Prerelease prior to the expansion set's release date, can I use cards from that set in a sanctioned tournament as long as those cards are reprints of already legal cards?
Per the current Play! Pokemon Tournament Rules Handbook you cannot use any new cards until the set is considered legal for tournament play (currently the 2nd Friday following that expansion's US market release date), however you can use a newer version of a reprinted card that is currently playable in the Standard or Expanded format immediately upon its official release.

If I use Boost Shake to evolve Togetic into Togekiss, can I use Togekiss' "Precious Gift" ability, or does the effect of Boost Shake prevent me from doing so?
Precious Gift takes place at the end of the turn, so you still get to do it after using Boost Shake.

If Veluza with the "Fillet Memento" Ability gets Knocked Out and has a Splash Energy attached to it, can I move the Splash Energy but still use its effect to return Veluza to my hand?
If you choose to move Splash Energy with Fillet Memento, Veluza will not be returned to your hand since it no longer has Splash Energy attached.

In a Standard Format game I use "Technical Machine: Evolution" and the two Pokemon I choose are both Raichu. Does the game still recognize that Raichu BREAK exists despite it not being legal for play in that format, therefore allowing me to search my deck?
No, since Raichu BREAK is not currently legal in Standard Format you cannot attempt to search for it.

I have Pokemon that were put into play during the turn I use Medicham V's "Yoga Loop" attack. I immediately get another turn from "Yoga Loop". Can I evolve those Pokemon during that new turn?
Yes, absolutely! If you take another turn after using Yoga Loop you have to do everything you would normally do as part of your turn, including evolving any Pokemon that were in play on the previous turn.

I use Psyduck's "Overthink" attack to cause flips to be treated as Tails whenever your opponent flips a coin on the next turn. But if my opponent plays Will, which allows the player to choose the outcome of the first coin flip required for an attack, does my opponent get to choose heads for their first coin flip or is it still tails due to "Overthink"?
Overthink will cause the flip to be treated Tails regardless of Will, since Overthink is in effect whenever your opponent flips.

If Wo-Chien's "Binding Greed" attack knocks out the Defending Pokemon does the attack effect apply to the new Active Pokemon?
No, the effect of Binding Greed happens to the Defending Pokemon prior to checking if it has been KO'd. It does not pass along to the next Active Pokemon; only the Pokemon that received the attack is affected.

If I have Deoxys (SWSH170 Promo) with all three "Fusion Strike", "Single Strike", and "Rapid Strike" properties in play, how much is Drapion V's "Dynamic Tail" attack discounted by for its "Wild Style" Ability?
While Deoxys is all three types of Strike Pokemon, it is still just one Pokemon and gives only one {C} reduction for Wild Style.
