Ok, I'll start with VG. Regenerator Tornadus?! That thing is going to be amazing, considering it has no other way to heal itself. Volt Absorb Thundurus also seems pretty good, although Prankster boosted T-wave is one of the reasons it's so good in the first place.
TCG....I think we're overreacting. Chances are they'll have some kind of drawback. 300 HP is also beatable with...let me think....almost EVERY Dragon type, not to mention the killer gets 2 prizes because it's an EX. Hydreigon OHKO'S it with a pluspower, Rayquaza OHKO'S it with three energy, and Garchomp two or OHKO'S it depending on how many Altraria are out. The problem is its going to force every deck in the metagame to run dragons in it, which decreases the variety of decks by a lot. Hopefully the drawback will be strong enough to stop that from happening.
