Always better sealed
Pokemon Card Strategy: So as far as strategy goes, since Krookodile's Ability needs to have Krookodile in the active Pokemon spot you'll want to make sure you can keep Krookodile out there as long as possible, so make sure and have three energy cards on it before you put it into the active Pokemon spot, then I would suggest using Thrash and doing 90 damage every turn to knock Pokemon out faster and using Potions and other HP restoring items to keep Krookodile alive longer, and if you flip heads hopefully the defending Pokemon won't have enough energy cards on it to attack
During the End Phase of the turn you activate this effect: You can target 1 Fairy-type monster in either Players Graveyard
To properly order the half-deck, put the card numbered "Aang Tutorial 20" or "Zuko Tutorial 20" at the bottom of the half-deck, followed by "Aang Tutorial 19" or "Zuko Tutorial 19," and so on
It makes no sense for pure collectors, for players its not an issue
It has a relatively powerful move for its time, which gives you additional coin flips for every Sabrina Pokemon you have in play
