YOU CANNOT confuse a learning experience with a competitive learning experience.
Do NOT make the mistakes I've made trying to "teach" your child to play competitively BEFORE he/she even gets an opportunity to enjoy the game non-competitively.
Focus on FUN first. Make random stuff that doesn't involve alot of PokePower setups and advanced set-up strategy.
Young Beginners LOVE theme decks. They don't have the competive experience to even care about how their deck sets up. They just wanna play. It's exciting for them if they even get to evolve!
My mistake (I'm hoping it's not too late to be yours as well) was getting my daughter involved in tournament play too soon. She used to wake up at 5 a.m. and get ME up asking "Daddy, you want to play Pokemon with me?"
She had a great spirit for playing the game ... win or lose... didn't matter; she just wanted to play.
I absolutely
ruined that spirit being
Overzealous and getting her to learn complicated strategies and decks and taking/dragging her off to tournments.
Just play.
Kids don't care about how Focused a deck is or metagaming... just sit down and ENJOY playing with your child.
DO NOT build a deck and hand it to your child (that's a crippling black hole).
Theme deck your child. Direct them on ways to make small improvements to that theme deck:
removing random pokes and adding a thicker featured poke line
maybe adding colorless attack support
more trainers/supporters (a few at a time so it's Exciting to finally hit one!)
The BEST way to ENABLE a child is to let them see a gradual effect of deck modifications.
It's good for them to experience the frustration of not getting cards they need or a deck being slow to set up.
They need to experience losses, so they have a tolerance for the nature of the game and they won't LOSE IT whenever their deck is overpowered or is just inadequate.
I'm going to have to write another "Parents of Pokemon" type article. I think I've made enough mistakes since the last one to be of some use to new PokeParents ... lol
OH .. .and to directly answer your question.
A grass with special conditions. (i.e. Venasaur)
Being able to continually inflict conditions makes the kid feel like a shrewd little wizard.
