Regigigas X and Regigigas Promo: I'll miss 1 hit KOing benched Garchomp C's and seeing those priceless stares from other players as to why I'm playing Gigas.
Lumineon SF: I never got a chance to use it again, kept on pushing it off.
Starmia LA: Such an amazing card and I didn't really get to use it.
Warp Point: Need an explanation?
Unown Q: Great for some decks.
Raticate AR: Such a great card and a great stand alone deck with Expert Belt and Q abuse.
Abomasnow SF: Never got to use it, sigh...
Steelix SF: Such a balanced Pokemon, good spread and decent all around.
Giratina Lv X: Best spread ever, the feeling of taking 4+ prizes in one attack and the expression on my opponent's faces are priceless
Giratina (Let Loose): My favorite tech in SpeedGar, amazing Power and great attack.
Gardevior PL: The Power gave life to a handful of my decks.
Manectric PL: Loved the Body, useful in a lot of decks.
Cherrim SF: That extra 10 damage can be amazing and has a pretty nifty attack to boot.
Snorlax Lv X: Only reason I never babied the deck further is because of Machamp SF, a great attack and power, combo'd with Snorlax CoL this guy is the best tank to come into format... If Machamp didn't exist.
Dusknoir SF and the X: One of my personal favorites, I love spread damage and sniping, along with draw power? Amazing.
Gengar SF: I know, broken card, over used, blah blah blah, still one of my favorite Pokemon and one of the few decks I ran for over a year.
Dawn Stadium: A card I wish I used just once more.
Dialga G X: I hate Vileplume and other pesky Poke-Body's such as Yanmega, Nidoqueen, Mewtwo and so on.
Alakazam 4 X: Only Alakazam in format and we're losing it, great card and overshadowed by Garchomp.
Rayquaza LA: Such an awesome card, energy recovery is amazing!
Torterra SF: I loved the Poke-Power and great attacks to go with it.
And so many more but I'm going to stop while I'm ahead.
