That's right, Kristya! I so called this when it wasn't in the structure deck. (It's true, read my earlier post about the tins) Let's take a minute to review what a crazy beast this card is.
LIGHT/8/Fairy/EffectIf you have exactly 4 Fairy-Type monsters in your Graveyard, you can Special Summon this card from your hand. When you do, add 1 Fairy-Type monster from your Graveyard to your hand. Neither player can Special Summon monsters. If this face-up card would be sent from the field to the Graveyard, it returns to the top of the owner's Deck, instead.
Ridiculous. Just by having 4 Fairy monsters in your Graveyard, you can Special Summon this massive monster for free, and instead of being sent to the Graveyard, it returns to the top of the deck to be used again. You also get to grab a Fairy from the Graveyard and add it to your hand. That means recycling Hyperion/Earth/Honest/Whatever to use again.
It's very easy to summon, especially with cards like Valhalla, Hall of the Fallen, which lets you Special Summon a Fairy from your hand if you control no monsters. The best part, however, is that once it's on the field, neither player can Special Summon, and there's no way your opponent will be able to attack over this thing with a Normal Summoned monster. That means they're going to have to waste resources, and most likely Kristya will just return to the deck to be used again.
These new tins will mean that anyone can have all the cards needed to build one of the most competitive decks in the TCG right now, Agents. The only expensive card left is Solemn Warning, which may just be in wave 2.
