Trainers » Giovanni's Scheme
If I play "Giovanni's Scheme" and choose one of its effects, can I change to the other effect later in my turn as long as I haven't attacked yet?
No. You choose which effect to use when you play it and you're locked in with that effect until the end of your turn.

Trainers » Forest of Giant Plants
With the "Forest of Giant Plants" Stadium in play, could I evolve from Oddish to Gloom to Vileplume all in the same turn?
Yes. Oddish can evolve into Gloom on the turn it comes into play, and since Gloom has come into play that turn the stadium would allow it evolve into Vileplume right away too.

Trainers » Wide Lens
Wide Lens says to apply Weakness and Resistance for attacks that do damage to the opponent's Benched Pokemon. This will not affect attacks that say "this attack isn't affected by Weakness, Resistance, or any other effects" or "ignore all effects including Weakness and Resistance"; Weakness and Resistance is still ignored for those attacks.

Attacks » Shatter | Trainers » Sky Field
Say the "Sky Field" stadium is in play and I have 8 Pokemon on my Bench. My opponent uses Salamence's "Shatter" attack to KO my Active Pokemon and discard the stadium. Do I promote one of my Benched Pokemon first, or do I reduce my bench size to 5 Pokemon before promoting?
When the Sky Field stadium is discarded during the attack, the bench size is reduced immediately before going any farther. So after promoting your new Active Pokemon there will be 4 Pokemon on your Bench.
