Once during your turn (before your attack), you may look at the top 4 cards of your deck and rearrange them as you like. This power can't be used if Machamp is affected by a Special Condition.

Machamp is Pokédex #068, generation 1 (Kanto). Machamp is a Stage 2 Fighting Pokémon with 120 HP. The card says it evolves from Machoke. In this catalog that name is Machoke (#067).
Machamp sits at 51/165 in Expedition Base Set, position 51 of 165. Before it is 50 Kingler, and after it is 52 Magby. The set belongs to the E-Card series. It was released on September 15, 2002. The printed size is 165, and the checklist is the same length. The listed rarity is Rare.
Terraforming is listed as Poké-Power. Once during your turn (before your attack), you may look at the top 4 cards of your deck and rearrange them as you like.

Count the number of Pokémon you have in play with damage counters on them. Flip a coin. If heads, this attack does 50 damage plus 10 more damage for each of those Pokémon. Weakness is Psychic ×2.

Machamp (#068) has 48 other cards in the catalog. Those other cards are in 30 sets. The other printings with a release date run from 1999 to 2023. The earliest other card is Machamp 8/102 in Base (1999). That card lists 100 HP, and this one lists 120 HP. The rarity there is Rare Holo, and here it is Rare. Ken Sugimori illustrated that card, and Shin-ichi Yoshida illustrated this one. Retreat cost there is 3, and here it is 2. 42 other cards of Machamp list a different HP.
The illustrator line reads Shin-ichi Yoshida. I count 50 other cards in the catalog with that illustrator.
Expedition Base Set set binder is where a full Expedition Base Set set goes. This card fills one slot there. A generation binder holds one card of each species. Machamp can fill a slot in Generation 1 binder (Kanto). I still need this card.
