The deck from Luis "Maverick" isnt death and taxes, his deck is the original Maverick deck, you can read in the first page how at the beginning the deck had vials.
He created the deck, of course there were another GW decks but he was the first to find the keys for making gw a deck to beat in legacy: Knights of reliquaries , vials, stoneforge + equipments,2 scryb rangers, wayfarers and mothers, not tarmogoyfs ... people from another countries took this decklist and played green sun's zeniths rather than vials, but he tested zeniths and he decided to continue playing vials.
Moreover he has been talking about his deck in Spanish forums since 2010
