I have seen a lot of broken cards, crap cards, wierd cards and some nerfed ones in my time...but Gyrados* really takes the buiscuit.
OK, first attack is all right, but GEEEEEEEZZZZZZZZZYYYYYYYYY what is up with All-Out Blast?!?!?!?! Think of the damage! Yeah, without Delecatty next turn you'll lose but still!! Not entirely sure it will see play outside Catty though.
Latios (and Latias) probably don't include EX's in the effect because it effects BOTH players. They are nice and in my opinion better than LunaRock as the only reason people play LunaRock is because of Cargo and Pidgeot and they're both EVOLVED.
Great stuff though, Gyrados*=Most nerfed card EVER!!
