This deck was designed by Patomaru. It takes advantage of the hand draw mechanics of Eternal, which forces the opening hands to have a predictable distribution of power and non-power cards. That is something that has been historically used in certain synergy decks, because having a really high power number in the deck helps with drawing some of the key pieces of the deck. The big addition is
Binding Agreement, which was the build around card for the most recent episode of Farming the Depths of Eternal. In this deck, it draws a whopping 12 cards at an average! With approximately 4 non-power cards being among them. Follow that up with a Send an Envoy to fill the board with 5/5 sentinels. Another fun play is playing Vodakhan from the market into Binding Agreement.
