I recently got into collecting again after 6 years (and before when I was a kid). I already have the completed NM Pokemon TCG Base Set, Jungle Set, Fossil Set and Rocket Set. I wanted to complete these so bad because of the nostalgia and I started to collect these when I was a kid. I can't stop looking at them. Maybe I can post pictures soon, they are all safe in Portfolios.
I have way too many cards, and the ones I list below are probably the best pulls I can think of right now, but... let me think xP
Dark Raichu (Rocket)
This card just holds so many memories dating back from when I was a kid. This was my best pull when I was young and started to collect Pokemon TCG. Also, my first Secret Rare and it's obviously untradeable. It still remains in my collection after all these years :3
Mew ex (EX Legend Maker)
I pulled this cards for about 5 years ago, I absolutely loved it because for one, I like Mew and the design of this card is simply beautiful :3
(shiny) Mewtwo (Ex Holon Phantoms)
Pulled this card at around the same time when I got Mew, I was buying a lot of booster packs while I was on vacation somewhere... :3
(shiny) Jolteon (EX Power Keepers)
Again, pulled this card at around the same time I got my Shiny Mewtwo I mentioned above :3
Walrein ex (EX Power Keepers)
I love Walrein in general, so I was pretty excited when I pulled this nice ex card :)
Zekrom (Plasma Freeze)
I got this nice card from a random Plasma Freeze booster when buying some X and Y Base Set Booster Packs.
Reshiram (RC 22 Radiant Collection)
Again, I got some other random booster packs while buying some FlashFire TCG Booster Packs. I was pretty excited when I pulled this one, because it's a beautiful card even though I only collect X and Y cards now :3
Kyurem ex (Next Destinies)
Pulled from another random Booster Pack I got along with some X and Y Base Set booster packs.
Delphox 26/146 (X and Y Base Set)
I was pretty excited I pulled this card because it was in one of my first Boosters from the X and Y Base Set, and I got the entire Fennekin line in one single Booster Pack :3
Emolga ex 46/146 (X and Y Base Set)
Pretty amazing, nice looking card. Emolga is kinda cute too ;)
Yveltal Ex 79/146 (X ad Y Base Set)
I was really excited when I pulled this card, it looks amazing!
Yveltal Ex FA 144/146 (X and Y Base Set)
Again, a really beautiful and awesome card :D
Mega Blastoise EX 30/146 (X and Y Base Set)
My first Mega Evolution card, they just look so amazing! I love the artwork of most Pokemon TCG cards, but the Mega Evolution cards have something special :3
Mega Kangaskhan EX 79/106 (X and Y FlashFire)
My second Mega Evolution pull, I got it when I bought my first couple of FlashFire Booster Packs. I was pretty amazed because those cards look awesome, and funny thing, I pulled this out of a Booster Pack which showed an actual Mega Kangaskhan on the front ;)
