In its Land Forme, Shaymin LV.X (Platinum, 126/127) can lend a hand to other Grass-type Pokémon in play. Its Thankfulness Poké-Body gives each of your Grass-type Pokémon an additional 40 Hit Points. Shaymin can't use Thankfulness on itself or other Shaymin, but watch the rest of your Grass Pokémon grow like weeds. Shaymin LV. LV.X's Seed Flare attack strikes for 40 damage, and allows you to choose any number of Grass Energy cards from your hand and attach them to your Pokémon in any way you like. If you do, you get to add another 20 damage for each Grass Energy you attached. This strengthens the Seed Flare attack and also assists other Pokémon in play. The Gratitude Pokémon is a definite team player!
