Each Pokémon in play (both yours and your opponent's) gets -20 HP. No more than 20 HP can be reduced by all Gravitation Poké-Bodies.

Metagross is Pokédex #376, generation 3 (Hoenn). Metagross is a Stage 2 Metal Pokémon with 130 HP. The card lists level 68. The card says it evolves from Metang. In this catalog that name is Metang (#375).
Metagross sits at 7/147 in Supreme Victors, position 7 of 153. Before it is 6 Magmortar, and after it is 8 Rayquaza C. The set belongs to the Platinum series. It was released on August 19, 2009. The printed size is 147. This checklist is longer, at 153 cards. The listed rarity is Rare Holo.
Gravitation is listed as Poké-Body. Each Pokémon in play (both yours and your opponent's) gets -20 HP. No more than 20 HP can be reduced by all Gravitation Poké-Bodies. The attack Geo Impact lists 60 damage. The cost is Metal, Metal, Colorless. If you have a Stadium card in play, this attack does 20 damage to each of your opponent's Benched Pokémon that is the same type as the Defending Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Weakness is Fire +30. Resistance is Psychic -20. Retreat cost is 3. The flavor text reads "Metang combined to form it. With four brains, it has the intelligence of a supercomputer."
Metagross (#376) has 33 other cards in the catalog. Those other cards are in 22 sets. The other printings with a release date run from 2004 to 2026. The earliest other card is Metagross 11/101 in Hidden Legends (2004). That card lists 100 HP, and this one lists 130 HP. Both list the rarity Rare Holo. Kouki Saitou illustrated that card, and Kagemaru Himeno illustrated this one. Retreat cost there is 2, and here it is 3. 31 other cards of Metagross list a different HP.
The illustrator line reads Kagemaru Himeno. I count 656 other cards in the catalog with that illustrator.
Supreme Victors set binder is where a full Supreme Victors set goes. This card fills one slot there. A generation binder holds one card of each species. Metagross can fill a slot in Generation 3 binder (Hoenn). I still need this card.
