Power Keepers is a set in the EX series. It was released on February 2, 2007. The printed size is 108, and the checklist is the same length. Armaldo is 3/108, in position 3 of 108 on this checklist. Before it is 2 Altaria, and after it is 4 Banette. The listed rarity is Rare Holo.
Armaldo is a Stage 2 Fighting Pokémon with 120 HP. In the Pokédex this is Armaldo (#348), generation 3 (Hoenn). The card says it evolves from Anorith. In this catalog that name is Anorith (#347).
Ken Sugimori illustrated this card. The same name is on 1,112 other cards in the catalog.
Armaldo (#348) has 8 other cards in the catalog. Those other cards are in 8 sets. The other printings with a release date run from 2003 to 2022. The earliest other card is Armaldo 1/100 in Sandstorm (2003). Both list 120 HP. Both list the rarity Rare Holo. Mitsuhiro Arita illustrated that card, and Ken Sugimori illustrated this one. 7 other cards of Armaldo list a different HP.
The attack Rock Blast lists no damage number. The cost is Fighting. Discard up to 5 Fighting Energy cards attached to Armaldo. For each Energy card you discarded, choose an opponent's Pokémon in play and this attack does 20 damage to those Pokémon. (You may choose the same Pokémon more than once.) This attack's damage isn't affected by Weakness or Resistance. Mach Claw is another attack lists 60 damage. The cost is Colorless, Colorless, Colorless. This attack's damage isn't affected by Resistance. Weakness is Grass ×2. Retreat cost is 3.
I keep a set binder for Power Keepers, meant to hold every card of that set. This card is one slot in the Power Keepers set binder. A generation binder holds one card of each species. Armaldo can fill a slot in Generation 3 binder (Hoenn). I still need this card.
