Legend Maker is a set in the EX series. It was released on February 1, 2006. The printed size is 92. This checklist is longer, at 93 cards. Sealeo is 43/92, in position 43 of 93 on this checklist. Before it is 42 Roselia, and after it is 44 Tangela. The listed rarity is Uncommon.
Sealeo is a Stage 1 Water Pokémon with 70 HP. In the Pokédex this is Sealeo (#364), generation 3 (Hoenn). The card says it evolves from Spheal. In this catalog that name is Spheal (#363). The card lists Walrein, Walrein (#365) under evolves to.
Midori Harada illustrated this card. The same name is on 352 other cards in the catalog.
Sealeo (#364) has 13 other cards in the catalog. Those other cards are in 12 sets. The other printings with a release date run from 2004 to 2024. The earliest other card is Team Aqua's Sealeo 16/95 in Team Magma vs Team Aqua (2004). That card is named Team Aqua's Sealeo, while this one is Sealeo. Both list 70 HP. The rarity there is Rare, and here it is Uncommon. T. Honda illustrated that card, and Midori Harada illustrated this one. 10 other cards of Sealeo list a different HP.
Power Circulation is listed as Poké-Power. Once during your turn (before your attack), you may search your discard pile for a basic Energy card, show it to your opponent, and put it on top of your deck. If you do, put 1 damage counter on Sealeo. This power can't be used if Sealeo is affected by a Special Condition. The attack Lunge Out lists 30 damage. The cost is Water, Colorless. Weakness is Metal ×2. Retreat cost is 1.
I keep a set binder for Legend Maker, meant to hold every card of that set. This card is one slot in the Legend Maker set binder. A generation binder holds one card of each species. Sealeo can fill a slot in Generation 3 binder (Hoenn). I still need this card.
