Pretty art at least.
HP: 60. Not going anywhere for a while.
Deep Sleep: Dark Gengar's pokemon power. A good effect, if pulled off right.
Yawn: Does damage and achieves the Deep Sleep effect nicely but the coin flip makes too much for a gamble.
Energy cost: Good for water decks, but not much else.
Retreat cost: Given Reli's slowness, two should be more apropos.
Overall: A good cheap status effect card if luck is with you with the attack but don't be dependant on it. Needs other cards so it becomes more of a failsafe.
