After time is called at the end of a match, what happens if I use Medicham V's "Yoga Loop" attack during the "plus three turns" part?
If you use Yoga Loop when time is called during your turn, you would then get "Turn 1" instead of your opponent. Likewise, if you use it during Turn 1 you would also get Turn 2 and your opponent would get Turn 3, and so on... However, if you use it on the final turn of the match you do not get an extra turn.
If my opponent flipped heads for Nymble's "Slight Splash" attack on their previous turn, what happens if I use Quaquaval ex's "Exciting Dance" attack? Does Nymble get switched out to the bench or not?
The effect of Exciting Dance is done to the protected Nymble, so Exciting Dance would not move it to the bench.
If I use Mawile's "Tempting Trap" attack to place an effect on the Defending Pokemon where it takes +90 more damage from attacks on my next turn, what happens if I use Duraludon VMAX's "G-Max Pulverization" attack on my next turn? Does it still do the +90 damage or not?
G-Max Pulverization says its damage isn't affected by any effects on your opponent's Active Pokemon, so the extra +90 damage would not be done. Bad move dude...
Does a Pokemon with multiple types such as Scovillain with the "Double Type" Ability count for two different types of Pokemon for Toxtricity's "Loud Mix" attack?
Yes, Loud Mix checks for the number of types of Pokemon on your Bench, not how many Pokemon there are.

If my Active Pokemon was attacked by Tsareena's "Queenly Heel" attack, can I evolve it if I switch or retreat?
Yes, going to the Bench removes the attack effect so you can evolve what was your Active Pokemon, and also your new Active Pokemon, if they are normally able to evolve.
