Yesterday's CotD was Regigigas EX from ND...I dunno, I loved the old Giggles decks, but this just doesn't fill that void. Statwise 180 HP is about average for an EX, x2 Weakness to is meh, no Resistance is common, and to Retreat is super expensive. Giga Power is...eh... for 60 isn't that great, and having to deal 20 to yourself to deal 20 more isn't that great. Still, that extra damage fuels his next attack, Raging Hammer, which for deals 50+ 10 more for each damage counter on Regigigas EX...again, I dunno, it's just not that good in actual use; sure he has a lot of HP to soak up attacks, but a lot (and I mean a lot) of the big attackers out there can easily 2HKO him, so while he can probably get a KO in before that, you're still losing 2 prices when he goes down, not to mention the big Energy investment. So yeah, it's a more powerful Outrage, but regular Zekrom and Reshiram don't cost you 2 prizes when KOed either and their version costs 2 Energy less.
Modified - 7/10 - I'm not sold on the hype, maybe it is better than I'm giving it credit for, but just conceptually, I see it more as an average EX people are going to forget about soon enough
Limited - 10/10 - Big, splashable into any deck, big...did I mention big? Of course, the other option is to store him away safely in a binder, but why not have some fun?
Unlimited - 2/10 - I dunno, there's ways to probably keep it alive, but ER and SER drain him pretty quickly of his ability to attack as well
