Yanmega is Pokédex #469, generation 4 (Sinnoh). Yanmega is a Stage 1 Grass Pokémon with 100 HP. The card lists level 53. The card says it evolves from Yanma. In this catalog that name is Yanma (#193).
Yanmega sits at 14/147 in Supreme Victors, position 14 of 153. Before it is 13 Venusaur, and after it is 15 Arcanine G. 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.
Speed Boost is listed as Poké-Power. Once during your turn (before your attack), if Yanmega is your Active Pokémon, you may search your discard pile for a Grass Energy card and attach it to Yanmega. This power can't be used if Yanmega is affected by a Special Condition. The attack Wind Return lists 20+ damage. The cost is Colorless, Colorless. You may return all Grass Energy attached to Yanmega to your hand. If you do, this attack does 20 damage plus 20 more damage for each Energy card you returned. Speed Dive is another attack lists 70 damage. The cost is Grass, Grass, Colorless, Colorless. Weakness is Lightning +20. Resistance is Fighting -20.
Yanmega (#469) has 19 other cards in the catalog. Those other cards are in 15 sets. The other printings with a release date run from 2008 to 2025. The earliest other card is Yanmega 17/146 in Legends Awakened (2008). That card lists 90 HP, and this one lists 100 HP. Both list the rarity Rare Holo. Kent Kanetsuna illustrated that card, and Masakazu Fukuda illustrated this one. 18 other cards of Yanmega list a different HP.
The illustrator line reads Masakazu Fukuda. I count 471 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. Yanmega can fill a slot in Generation 4 binder (Sinnoh). I still need this card.
