-1 Dark Armed
+1 Trance Archfiend
Dark Armed is a win more card to me, atleast in Dark Worlds and Trance Archfiend adds more consistency
-2 Beiige
-1 Raven
+1 Deck Devi
+2 Skill Drain
I know you can go into Dark Highlander, but raven is a pretty bad discard outlet IMO without beiige, and if you have beiige you cant discard anything else if you want to bring out dark highlander. Deck Devi hits a lot of the decks in the format and the upcoming one's. Skill Drain is just extremely nice to have, and if you learn to play it right it will almost never conflict with TGU.
