Evolution

How Basic Pokémon grow into Stage 1 and Stage 2 Pokémon.

How it works

Evolution is the central building block of the Pokémon TCG. Most decks start with Basic Pokémon on the table. A player can then place a matching Stage 1 card on top, and later a Stage 2 card, to replace it with a stronger version.

The rule mirrors the video games, where a Charmander becomes Charmeleon and then Charizard. Each evolved card names the Pokémon it evolves from, so you can only chain cards that belong to the same line.

Evolution gives the game a built-in tension. Stronger cards need set-up time, and the opponent gets chances to interrupt. That is why deck builders often include several copies of the Basic Pokémon in a line.

On a card, look for the stage label near the top and the small line that names the Pokémon it evolves from.

In practice

An example in play

Say you open a game with a Charmander as your Active Pokémon. In your hand you hold a Charmeleon, a Fire Energy and a second Basic Pokémon. On your first turn you attach the Energy and put the second Basic on the Bench. You wait on the Charmeleon, because the usual rules do not let you evolve on the very first turn of the game.

On your next turn you place Charmeleon on top of Charmander. The Energy stays attached, so nothing you invested is lost. A few turns later, if you draw Charizard from Base Set, it goes on top of Charmeleon. Your opponent had several turns to prepare for that moment, which is the price of a big Stage 2 card.

The same idea works in miniature with Pikachu, a Basic that can grow into Raichu. For a modern version of the Charmander climb, open Charizard ex from the 151 set. It also evolves from Charmeleon, so the line you just practiced still works.

Common mistakes

  • Evolving a Pokémon the turn it arrives. The usual rule says a Pokémon cannot evolve on the turn you first played it. Bench your Basic one turn early.
  • Mixing up lines. A Stage 1 card only fits on the Pokémon it names. A random Stage 1 will not do.
  • Evolving the same Pokémon twice in one turn. A Pokémon that already evolved this turn has to wait.
  • Playing only one Basic. If that single Basic is knocked out, the evolution cards in your hand have nowhere to go.

Some special cards bend these limits, so check the rulebook for the exact wording.

Questions readers ask

Do I lose my Energy when I evolve?

No. The Pokémon underneath keeps its attached Energy, and it normally keeps its damage counters too.

Can a Stage 2 card go straight onto a Basic?

Under the normal rules, no. A Stage 2 goes on a Stage 1, and the Stage 1 goes on a Basic.

Does every Pokémon have to evolve?

No. Mewtwo in Base Set is a Basic that never evolves, and it is still a collector favorite.
