Base–Neo

The most oppressive deck in early TCG history. Sneasel dealt up to 100 damage for 1 Energy while Slowking's mistranslated Mind Games power denied Trainers from the bench. In the all-cards-legal environment, this combination was nearly unbeatable and directly led to the creation of the Modified format and the first ban list.

Feraligatr's Riptide attack dealt 10 damage plus 10 for each Water Energy in your discard pile — scaling to massive damage as the game progressed. The deck used Misty's Wrath and Trash Exchange to fuel the discard pile. Feraligatr dominated the first Modified format events once Sneasel was banned.

Typhlosion's Heat Tackle hits for 80 damage while Pokémon Tower prevents Recycle Energy from working. Runs a full 4-4 Energy removal suite to starve opponents of resources. Blaine's Charmander provides a low-cost backup attacker. A top-tier aggressive deck.

Brock's Ninetales uses Shapeshift to copy Steelix's attacks, creating a beefy attacker resistant to Energy Removal thanks to Metal Energy and Recycle Energy. Gold Berry and Healing Field keep attackers healthy. Brock's Protection prevents bench damage.

Kingdra attacks with Genetic Memory for a single Colorless Energy, copying Seadra's attacks at 90 HP. Pokémon Center heals all damage, and Focus Band gives extra survivability. Pichu clears Baby Pokémon from benches. A consistent, efficient Stage 2 deck.

Chansey equipped with Metal Energy becomes extremely tanky — Metal reduces damage taken by 10 per card while Double Edge hits for 80. Healing Field and Gold Berry restore HP, while Energy Charge recovers discarded Special Energy. Won the 2002 World Championship Professor Division.

Dark Crobat uses Hyper Devolution Spray to repeatedly devolve itself, re-triggering Dark Golbat's Pokémon Power which places damage counters when it comes into play. Sneasel's Beat Up provides raw damage output. An expensive but devastating combo deck.

Dark Vileplume's Hay Fever locks both players out of Trainers, then Dragonite's Step In ability lets you swap around Confusion from Dark Gloom's Pollen Stench. Play your Trainers, promote Dark Vileplume to lock, then Step In with Dragonite to attack.

Murkrow traps the opponent's Pokémon Active with Mean Look, Dark Vileplume blocks all Trainer cards (including Switch and Warp Point), and Erika's Victreebel uses Fragrance Trap to pull targets from the bench. Smeargle converts opponent Pokémon to favorable types. A devastating lock/control deck.

Rocket's Zapdos deals 70 damage with Electroburn, with Metal Energy reducing the self-damage. Muk shuts down all Pokémon Powers, crippling Slowking, Cleffa's Baby Rule, and other key abilities. Runs a full 4-4 Energy removal suite. Aggressive and disruptive.
