Basic, Stage 1 and Stage 2: how evolution works in the Pokémon TCG
For beginners Published 2026-10-13

Evolution is the part of the Pokémon TCG that surprises new players most. A small Pokémon that cannot fight well on its own turns into a much stronger one, but only if you follow a few precise rules. This article explains all of them with the wording of the official rulebook, plus the special cases that new sets keep adding.
The three stages
Look at the top-left corner of any Pokémon card. It shows the card's Stage: Basic, Stage 1 or Stage 2. The rulebook calls Stage 1 and Stage 2 cards Evolution cards, and says they are played on top of a Pokémon already in play.
| Stage | How it enters play | What the card shows |
|---|---|---|
| Basic | Played directly from your hand onto your Bench, or chosen as your Active Pokémon during setup | Nothing under the Stage label |
| Stage 1 | Played on top of the Basic Pokémon it evolves from | "Evolves from" and the Basic's name |
| Stage 2 | Played on top of the Stage 1 Pokémon it evolves from | "Evolves from" and the Stage 1's name |
A Basic Pokémon is the only kind you can start a game with, which is why every deck must contain at least one. If you open with no Basic Pokémon in your first 7 cards you take a mulligan: reveal your hand, shuffle it back and draw again.
How to evolve, step by step
- Find the Evolution card in your hand. Read its "Evolves from" line. It names the Pokémon you need.
- Check that the Pokémon was in play at the start of your turn. The rulebook says the Pokémon must be one you had in play at the beginning of your turn.
- Put the Evolution card on top of it. The old card stays underneath. You can evolve your Active Pokémon or any Benched Pokémon.
- Keep going if you can. A Basic can become a Stage 1, and a Stage 1 can become a Stage 2, but only one step per Pokémon per turn.
The rulebook's own example: Susan has a Greavard in play and a Houndstone card in her hand that says "Evolves from Greavard". She plays Houndstone on top of Greavard and keeps any damage counters. Real cards you can look up in our archive show the same pattern. For instance, Quaxwell is a Stage 1 whose card says it evolves from Quaxly.

The timing rules that trip people up
- Not on the turn it arrived. A Pokémon that came into play this turn cannot evolve this turn. Putting a Basic on the Bench and evolving it immediately is not allowed.
- Not twice in one turn. When you evolve a Pokémon it counts as new in play, so it cannot evolve again the same turn.
- Not on your own first turn. Neither player may evolve a Pokémon on that player's first turn, unless a card says so.
- As many as you want. Within those limits you may evolve as many different Pokémon as you can in a single turn.
What an evolved Pokémon keeps and loses
When a Pokémon evolves it keeps every card attached to it, including Energy cards and the earlier Evolution cards, and it keeps its damage counters. It loses Special Conditions such as Asleep, Confused or Poisoned, and any effects of attacks that were on it. Evolving is therefore one of the ways to cure a Pokémon.
The evolved Pokémon also becomes a different card, so it has its own HP, attacks, Weakness and Retreat Cost. It cannot use the attacks or Abilities of its previous stage unless a card says so. Because it keeps the damage counters but gets a larger HP, a wounded Basic Pokémon often becomes much safer after it evolves. Compare the damage counters with the new HP, not the old one.
Glossary terms worth knowing here: an evolved Pokémon is one that has another Pokémon under it, and to devolve is the opposite of evolving, done by certain cards. A devolved Pokémon also loses its Special Conditions and effects.
Names matter: the special cases
An Evolution card evolves from a Pokémon with a specific name, and in some cards the name has extra words. The rulebook gives three cases that new players often miss.
Pokémon ex
The "ex" is part of the name. Miraidon and Miraidon ex are different names, so a deck can have up to 4 of each. When a Pokémon ex is Knocked Out, your opponent takes 2 Prize cards. Pokémon ex and the older Pokémon-EX are not the same name either.
Trainer's Pokémon
A Pokémon with a Trainer's name in its title, such as Iono's Tadbulb, is a different card from the ordinary Tadbulb. The rulebook says Iono's Bellibolt ex can evolve from Iono's Tadbulb but not from a regular Tadbulb. The same logic keeps a regular Sandshrew from evolving into "Brock's Sandslash".
Mega Evolution Pokémon ex
In the Mega Evolution Series, Mega Evolution Pokémon ex follow normal evolution rules with a twist: Mega Gardevoir ex evolves directly from Kirlia, Mega Lucario ex evolves directly from Riolu (not from Lucario or Lucario ex), and Mega Kangaskhan ex can be put directly into play as a Basic Pokémon. They count as Pokémon ex, so effects that help Pokémon ex help them too, and when one is Knocked Out your opponent takes 3 Prize cards.
Evolution and Prize cards
Power comes with a price. Stronger kinds of Pokémon give your opponent more Prize cards when they are Knocked Out, and the first player to take all their Prize cards wins.
| Kind of Pokémon | Prize cards your opponent takes |
|---|---|
| Ordinary Pokémon (Basic, Stage 1, Stage 2) | 1 |
| Pokémon ex and Tera Pokémon ex | 2 |
| Pokémon V and Pokémon VSTAR | 2 |
| Pokémon VMAX | 3 |
| Mega Evolution Pokémon ex | 3 |
A Tera Pokémon ex also takes no attack damage while it sits on your Bench. These values come from the glossary and appendices of the official rulebook; always read the card itself, because it can add its own rules.
Why evolution lines need planning in a deck
Because a Stage 2 needs a Stage 1, and a Stage 1 needs a Basic, one missing card breaks the chain. The rulebook's deck-building advice is practical: collect up to 4 copies of your favourite Pokémon, and, if it evolves, try to get 4 of each Pokémon in its evolution chain as well. Remember the 4-copy limit applies per name, so a Pokémon and its ex version count as separate names.
It also explains why decks hold many Basic Pokémon: they are the only cards you can play from the start. Radiant Pokémon are a related special case: they are always Basic, never evolve from or into another card, and a deck can hold only one.
A quick self-test
- You put a Basic Pokémon on the Bench this turn and hold its Stage 1. Can you evolve it? No. It came into play this turn.
- It is your first turn of the game and you hold a Stage 1 for your Active Pokémon. Can you evolve? No. Nobody evolves on their own first turn unless a card says so.
- Your Poisoned Pokémon evolves. Is it still Poisoned? No. Evolving removes Special Conditions.
- Your damaged Pokémon evolves. Do the damage counters stay? Yes.
- You hold Iono's Bellibolt ex and a plain Tadbulb is in play. Can you evolve it? No. The names differ.
This article describes the rules in the official rulebook last updated in September 2026. Cards can create exceptions, and newer rulebooks may change details, so treat the card text as the final word.
