You pay Colorless less to retreat Arcanine for each Energy attached to it.

Aquapolis is a set in the E-Card series. It was released on January 15, 2003. The printed size is 147. This checklist is longer, at 182 cards. Arcanine is H2/147, in position 152 of 182 on this checklist. Before it is H1 Ampharos, and after it is H3 Ariados. The listed rarity is Rare Holo.
Arcanine is a Stage 1 Fire Pokémon with 90 HP. In the Pokédex this is Arcanine (#059), generation 1 (Kanto). The card says it evolves from Growlithe. In this catalog that name is Growlithe (#058).
Kyoko Umemoto illustrated this card. The same name is on 174 other cards in the catalog.
Arcanine (#059) has 41 other cards in the catalog. Those other cards are in 35 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Arcanine 23/102 in Base (1999). That card lists 100 HP, and this one lists 90 HP. The rarity there is Uncommon, and here it is Rare Holo. Ken Sugimori illustrated that card, and Kyoko Umemoto illustrated this one. 36 other cards of Arcanine list a different HP.
Extreme Speed is listed as Poké-Body. You pay Colorless less to retreat Arcanine for each Energy attached to it. The attack Fire Blow lists 30+ damage. The cost is Colorless, Colorless, Colorless. You may discard any number of Fire Energy cards attached to Arcanine when you use this attack. If you do, flip a number of coins equal to the number of Fire Energy cards you discarded. This attack does 30 damage plus 30 more damage for each heads. Weakness is Water ×2. Retreat cost is 3.
I keep a set binder for Aquapolis, meant to hold every card of that set. This card is one slot in the Aquapolis set binder. A generation binder holds one card of each species. Arcanine can fill a slot in Generation 1 binder (Kanto). I still need this card.
