Is this a good pokemon deck?

What is a good pokemon tcg deck for a tournament?

• I'm 10. Here is my deck. 1 Shaymin 2 double full heals 1 dusk ball 2 energy searches 4 potions 2 mom's kindness 1 rainboy energy 4 electrikes 2 manectrics 3 pikachus 3 piplup 1 double rainbow energy 8 water energies 8 electric energies 6 leaf energies 2 prinplups 1 empoleon 2 shuppets 2 bannete ex 1 jolteon 1 glaceon 3 eeves

• Answer:

  This is very weak and the bannete ex is illegal. Get rid of Shaymin, no reason to have 6 leaf energies to power up one basic grass card. You need some stronger cards, you have too many basic or stage one cards. The easy way to tell if a card is illegal is look at the weakness. If it just has a symbol without any numbers beside it they are too old to use in a tournament. My advice is to take all your cards to where they hold the tournaments and others will help you to create a better deck.
