AbilityPrimal Veil
As long as Armaldo is your Active Pokémon, each player can't play any Supporter Cards.

Armaldo is Pokédex #348, generation 3 (Hoenn). Armaldo is a Stage 2 Fighting Pokémon with 120 HP. The card says it evolves from Anorith. In this catalog that name is Anorith (#347).
Armaldo sits at 1/100 in Sandstorm, position 1 of 100. The next card is 2 Cacturne. The set belongs to the EX series. It was released on September 18, 2003. The printed size is 100, and the checklist is the same length. The listed rarity is Rare Holo.
Primal Veil is listed as Poké-Body. As long as Armaldo is your Active Pokémon, each player can't play any Supporter Cards. The attack Blade Arms lists 60 damage. The cost is Fighting, Fighting, Colorless. Weakness is Grass ×2. Retreat cost is 3.
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 2004 to 2022. The earliest other card is Armaldo ex 16/17 in POP Series 1 (2004). That card is named Armaldo ex, while this one is Armaldo. That card lists 160 HP, and this one lists 120 HP. The rarity there is Rare, and here it is Rare Holo. Hikaru Koike illustrated that card, and Mitsuhiro Arita illustrated this one. 7 other cards of Armaldo list a different HP.
The illustrator line reads Mitsuhiro Arita. I count 721 other cards in the catalog with that illustrator.
Sandstorm set binder is where a full Sandstorm set goes. This card fills one slot there. A generation binder holds one card of each species. Armaldo can fill a slot in Generation 3 binder (Hoenn). Themed lists that include this exact card are Mitsuhiro Arita cards. I still need this card.
