15 Common Pokémon TCG Rules Mistakes (and How to Avoid Them)
The rules beginners and even experienced players get wrong most often in the Pokémon TCG: first-turn limits, Energy and Supporter limits, Weakness on the Bench, evolving, Special Conditions and Prize cards.

Most rules disputes at a kitchen table or a local league come from the same short list of mistakes. Some give one player an unfair advantage; others just slow the game down. Here are the fifteen we see most, grouped by when they happen, with the correct rule for each.
Setting up
1. Drawing Prize cards before checking for Basic Pokémon
The correct order is: draw 7, place your Basic Pokémon, mulligan if you have none, and only then set aside 6 Prize cards. If you set Prizes first and then mulligan, you have to undo everything. See going first and mulligans.
2. Forgetting the opponent’s extra cards after a mulligan
When your opponent mulligans, you may draw one extra card for each of their mulligans. It is optional, but most players take it. If both players mulligan, the shared mulligans cancel out.
The first turn
3. Attacking when going first
The player who goes first cannot attack on their first turn. This applies even if they have the Energy for an attack that costs nothing.
4. Playing a Supporter when going first
The first player also cannot play a Supporter on their first turn. Items, Stadiums, Tools, Abilities, Energy attachment and retreating are all still allowed.
5. Evolving on the first turn
Neither player can evolve on their own first turn, and nobody can evolve a Pokémon the turn it was put into play. The player going second also has to wait until their second turn to evolve.
Every turn
6. Forgetting to draw at the start of the turn
Every turn begins with a draw, including the first player’s first turn. If you realise you forgot, tell your opponent straight away; it is much easier to fix early.
7. Attaching more than one Energy
You can attach one Energy card from your hand per turn, to any one of your Pokémon. Abilities and attacks that attach Energy are separate and do not count towards this.
8. Playing a second Supporter
Only one Supporter per turn. If you play a Supporter and it draws you into a better one, the better one has to wait until next turn.
9. Retreating twice
You can retreat only once per turn. Switching with a card effect, such as an Item that switches your Active Pokémon, does not count as retreating, so you can still do both. See retreating and switching.
10. Playing a Stadium with the same name
You cannot play a Stadium if one with the same name is already in play, even if it is your opponent’s. You can play a different Stadium to replace it.
Damage
11. Applying Weakness and Resistance to Benched Pokémon
Weakness and Resistance only apply to damage to the Active Pokémon. When an attack also does damage to the Bench, that damage ignores Weakness and Resistance unless the attack says otherwise. More in how damage is calculated.
12. Applying effects in the wrong order
Work out damage in this order: base damage and the attack’s own text, then effects on the attacker, then Weakness (×2), then Resistance (−30), then effects on the defending Pokémon. Doing Weakness last can change the result by a lot. The damage calculator applies the order for you.
Special Conditions
13. Keeping Special Conditions after evolving or retreating
When a Pokémon evolves, or moves to the Bench (by retreating or switching), all of its Special Conditions are removed. An Asleep or Paralyzed Pokémon cannot retreat, but a switching card can still move it. See Special Conditions explained.
14. Skipping Pokémon Checkup
Poison and Burn damage, and the coin flips to wake up or recover from a Burn, happen in Pokémon Checkup after every turn, not just your own. Paralysis ends during the Checkup after its owner’s next turn. Leaving these until “later” is how games end with the wrong HP.
Prize cards
15. Taking the wrong number of Prizes
A Pokémon ex gives up 2 Prizes, a Mega Evolution Pokémon ex gives up 3, and most others give up 1. The rule box on the card tells you. When several Pokémon are Knocked Out at once, the attacking player takes Prizes for each. See Prize cards and winning.
How to avoid them
- Say your actions out loud: “attach Energy, play Supporter, attack.” Your opponent can catch a mistake before it matters.
- Use a tracker. PTCG Companion has toggles for Energy, Supporter, Retreat and Ability that reset when you tap Turn ➔, runs Pokémon Checkup for you, and shows each player’s Prizes.
- Fix mistakes immediately. In casual play, players usually rewind a small mistake if it is spotted straight away. At an event, call a judge rather than fixing it yourselves.
