This is my version of Great Tusk mill. The one card that differs from other decks is the Banette. Most players would agree that explorer's guidance is an overall bad card, it mills you faster than your opponent! So I just looked through all my bulk, and I found something to counter the need of Ancient Supporters. However, Azul GG did come up with a deck with no explorer's guidance, but I think that is to inconsistent, so much so that I even included one copy in the deck as backup. The other difference with this deck is that there is only one Ancient booster capsule, simply because it dosen't give you enough hp to survive really anything appart from Charizard ex's first attack (before it has taken a prize). Hero's Capr however is actually helpful, giving a big enough hp boost to Arceus, Charizard with one prize taken, and Lugia vstar! The last interesting card is Hand Trimmer which allows you to discard lots of cards in your opponent's hand which they have accumulated through out the game, and gets energy in the discard.
Hope you like milling!
