Pokemon Card Market Index Tracker

[Latios375]

If you were to create an index tracker for the entire hobby, what cards would you include?
I was thinking of an index that covers every era and diversifies the characters a bit.

I would consider tracking cards like:
Base Set Charizard Unlimited
1st Ed. Dark Blastoise
1st Ed. Shining Gyarados
1st Ed. Lugia
Crystal Kabutops
Gold Star Rayquaza
Celebi ex Unseen Forces
Glaceon Lv.X
Milotic Secret Supreme Victors
Mew Prime
Zekrom EX Next Destinies
Emploeon Secret Plasma Freeze
Mewtwo EX Secret #164 Breakthrough
Mario Pikachu
Charizard Secret Burning Shadows
Scream Promo Psyduck
Latias & Latios Alt Art
Moonbeon

I was going to reference the same thing. TCG Fish has been a great resource for me and I recommend it to everyone. They also have a handy app!
