What happens if my opponent failed a Confusion check last turn and I try to use Sudowoodo's "Watch and Learn" attack? Would Sudowoodo take 3 damage counters?
If the Pokemon failed its attack because of Confused, an attack was not used. Sudowoodo's Watch and Learn would simply do nothing.

The Burned special condition has changed from Sun & Moon and onward. Now when a Pokemon is Burned in between turns you first put two damage counters on that Pokemon then flip to see if the Burned condition is removed (heads) or if it remains (tails).

If my Confused Pokemon tries to use a GX attack and flips Tails, does that use up my "one GX attack per game"?
No, if you flip tails the attack fails and you don't use up your GX attack.

Checking for Confusion should be the very first thing you deal with after you announce what attack you want to use. Contrary to the "Full Details of Attacking" steps found in some older rulebooks, it must be done prior to making any choices the attack requires (such as choosing an opponent's Pokemon), paying any costs (such as discarding energy), flipping a coin to see if the attack fails, etc. So as soon as you announce which attack you are going to use, you must check for Confusion immediately before proceeding with any requirements of the attack or effects on the attacking Pokemon.

In the new Tournament rules, it is said that when time is called, the active player is allowed to finish his or her turn. After this, do players still check for Burn, Poison, and other relevant Special Conditions, or is the game over before the Special Conditions can take place?
When time is called, the end of the game would trigger at the end of the current player's turn after resolving all of the effects that occur during that player's turn, but before addressing any actions that happen between turns such as Special Conditions.

When both Active Pokemon are Asleep, who tries to wake up first?
Umm, we have no idea why it would matter. Usually you do them at the same time. If for some future reason it would matter, then the player whose turn is next would flip first.

If you "Paralyzed" your opponent's Active Pokémon and then use an attack that says "Flip a coin. If heads, your opponent's Active Pokémon is now Confused.", is that attack a forced check or optional?
It is a forced check.

Can you explain the process of Paralysis for me?
I paralyze your Pokémon on MY TURN. On YOUR TURN its Paralyzed, and at the end of YOUR turn it is UNPARALYZED. Back on MY TURN, it is NOT PARALYZED, comprendez?

If my Pokémon fell asleep and it wakes up next turn, will it be able to attack on that turn or the next?
You flip at the end of each player's turn. If it wakes up after the other players turn, BEFORE yours then it would act normal on your turn.
