Scenario: It's down to one prize each, your turn with 10HP left, and you're poisoned. You attack and KO your opponent to draw your last prize. But you take poison damage and would be KO'd now too. Do you win or does it go to Sudden Death?
You win, you must complete the rest of the combat sequence, but then if you win BEFORE the end of the turn, you win, period. Poison doesn't happen until after the end of your turn.

I was playing with this guy and he rearranged the order of the cards in his deck prior to shuffle it, would this be allowed in a tournament?
Yes but you would have the right to shuffle it yourself or cut it as well if you were uncomfortable with his shuffling method.

Do you apply Pokémon Powers before status effects?
Check under 'How do you figure damage' in the Pokémon rules. Existing status effects are applied first, then Pokémon powers, then damage is assigned, then lastly new status effects from the attack are applied (basically).

During a game is it legal to count your Discard pile? Is it also legal to count your deck as long as you do not look at the cards front?
Sure, though if you do it too often during a timed tournament it could be deemed stalling.

Is it illegal to randomly shuffle your deck, and if yes what are the penalties from doing so?

Is there any penalty for accidentally seeing your opponents hand?
As long as you both agree it was accidental, then no.

If Gastly (Fossil) uses Lick and Knocks Out the other Pokémon, does your opponent bring out another Pokémon and then you do the status effect?
No, a Pokémon is SLATED to be removed when it has sufficient damage assigned to it. Attack effects resolve BEFORE a replacement Pokémon is brought up.

This is probably an incredibly silly question, but I can't find the answer to it anywhere. If an opponent knocks out one of my Pokémon, and they forget to draw a prize, are they entitled to it if they remember later?
Technically yes. It is the responsibility of BOTH players to make sure everything is done correctly. If you spot it and he forgets you can BOTH get a warning in a tournament if you don't catch it.

What is a marked card?
A card that you can tell what it is by a glance (without seeing the front). It might have a different back, be scratched or written on in some way, be more worn out than the other cards, etc."
