Similar reason as to why Nomi is in the list. This decks cycles fast though the deck (Having 2xCristal Merchant, 2xWrath, 1x Thalnos and specially 2x Nourish), so Zephrys is there because is not that rare that you get to a point of being able to activate him in the late game (even before running out of a deck cos you can easily have 5-7 cards left and no duplicates).
Unlike Highlander decks, you should not expect to be able to activate him ever in the early game tho.
