Pokemon Card Strategy: So as far as strategy goes, this would be an amazingly good card to pair with Kyogre EX from this same set because Kyogre EX has a move that does 50 damage to 2 of your opponent's Pokemon so you could put Groudon in for awhile, spread damage around for quite a few turns with Tromp and then put Kyogre into play and use the move that does 50 damage to 2 Pokemon, or you could do it the other way, use Kyogre's move that spreads damage around a few turns, then retreat it for free with its first move, put Groudon into play and then use Giant Claw and do 120 damage every turn since the Pokemon you'll be facing should all have damage on them
It also blocks just about all common 2-drops, including several of the job select ones that I otherwise like
Being an enchantment is pretty cool since it's harder to remove than a random creature, plus the actual effect of preventing damage helps to stabilize you in the later turns of the game
It certainly wont stop them from attacking you with their Pokemon and taking Prizes to fill their hand back up
Pulling out the Enchanted version in your deck would be a great flex, and it comes with making Mr.Incredible stronger, alongside potentially drawing you a card
Lots of Creatures : Please note that if I load down my deck with too many non-Deep Sea stuff then we won't reliably be hitting a double trigger, but we will be getting a lot of value triggers
