Well, these two are part of my own set I'm working on, but since these (And a Drapion) are all I've finished, I may as well post them here as a sampling:
Giratina lv.51 - Psychic - 100HP
Basic
Poke-Body: Specter Sector
Each of your Giratina in play pays [C] less to retreat for every Giratina and Giratina Lv.X in play.
[P][P] Dimension Shift: Flip two coins. If one of them is heads, prevent all effects of attacks, excluding damage, done to Giratina by your opponent's Pokemon during your opponent's next turn. If both of them are heads, prevent all effects off attacks, including damage, done to Giratina during your opponent's next turn. If neither of them are heads, this attack does nothing.
[P][P] Origin Blast: 50 Damage
Weakness: Dark (+30)
Resistance: Psychic (-20)
Retreat: 3
Giratina Lv.X - Psychic - 140HP
Level-Up
Poke-Power: Damage Rift
Once During your turn (Before your attack) you may move up to 2 damage counters from one of your opponent's Pokemon to another. You cannot use more than one Damage Rift Poke-Power per turn.
