Yep, I wrote my comment before have pictures of the ancient Pokemons, thought Jigglypuff attack was based on damage on the opponents Pokemon So that make easy to know what ancient special energy will do, any energy but it damages the Pokemon
This is not an exhaustive list, but does contain some of the most common and widely-used hand traps
Needless to say, many kids probably lied about their birthdays to try to get the full effect of the attack and the card was eventually banned in tournaments for this reason
Of course there are other places the deck has trouble, but these are the primary areas
It used to be that it took a lot for cards from Commander precons to spike because their supply was so high, but now Commander itself is so huge (and we get so many more precons, which diffuses demand between multiple decks rather than everyone buying the yearly release) that this has changed
Each Commander Deck contains: 1 Ready-to-Play Deck of 100 Cards 10 Double-sided Tokens 1 Deck Box 1 Strategy Insert 1 Reference Card Magic 's most popular multiplayer format
