Articuno EX is one of the most special Pokemon in the Pokemon series because its name has the word 'one' in Greek (uno). I like this because it sure has a high HP and cheap moves.
This card can make a great combo with Plasma Frigate (from Plasma Storm). Plasma Frigate can make all Pokemon with Plasma Energy in play has no weakness. That means even your opponent's Pokemon is the weakness of Articuno EX, there's nothing to be worry. Also, trainer card Colress Machine (from Plasma Storm) can help you search for a Plasma Energy in your deck. This makes Articuno EX's attack Frost Prison more powerful because it said that if Articuno EX has any Plasma Energy attached to it, the defending Pokemon is now paralyzed. OMG! Your opponent doesn't need to play. He or she already loses unless he or she has Full Heal.
Like I just said, it can make a combo with Plasma Frigate and Colress Machine. And I forget one more. It is Deoxys EX. Deoxys Ex can make all your Team Plasma Pokemon add 20 more damages to the attacks, except all Deoxys EX. You can't find it on this website now. It is from the new expansion, Plasma Freeze.
If you are worried that your opponent will use Articuno EX, put more Full Heal in your deck. Also, use a Metal type deck or Pokemon with Water resistance, like Serperior or Bellossom.... Also, with cards that can discard Stadiums, or just put more Stadiums, then you can discard Plasma Frigate when you put your Stadiums in play.
Its advantage that it has high HP and Powerful moves. It can KO all your Pokemon first before it is KO.
Its disadvantage is that it has weakness against Metal type, that's all.
Its art is very beautiful like it is popped out of your card or splashing you.
I give 9 points out of 10. It is a beautiful card with magnificent moves and high HP. But it has weakness against Metal. That's bad.
