Today's CotD is Shaymin Lv X (Land) from PT. Now, whenever you hear Shaymin Lv X mentioned, you have 2 choices: this or the Sky form. Odds are, they mean this one.
Stat-wise, Shaymin Lv X is solid, with 100 HP, (could be better, but still a 30 HP improvement), x2 Weakness to :fire: (lol, :fire
, -20 Resistance to :water: (always helpful) and costing a cheap :colorless to Retreat. Thankfulness, of course, is the main reason for even using a Shaymin; giving all your :grass: Pokemon (excluding Shaymin Lv X) an extra 40 HP is a great boon for many :grass: oriented decks. Notably, it turns Torterra into an absolute beast for most opponents to KO. Seed Flare is also a great attack; though it may seem overpriced initially at :grass::colorless:colorless for 40, it lets you attach as many :grass: Energy from you hand as you want to your Pokemon, and increases Seed Flare's damage by 20 for each one, letting you easily power up your Pokemon and meat out big damage.
Modified - 8/10 (Would be better if Dialga G Lv X wasn't around, but he's still a great addition for any :grass: decks)
Limited - 7/10 (If you can get him, his pre-evo, and a bunch of :grass: Pokemon, you're good. Otherwise, stick him in the binder)
Unlimited - 2/10 (Not many :grass: Pokes besides, say, Fossil Muk or Vileplume EX, but they do fine on their own)
