While you can name Relic of Progenitus or Nihil Spellbomb, I dont recommend siding Needle in the blind versus decks that dont have other relevant cards to name
(Oh, and this requested list includes any exclusive trainers as well, banned, etc.) I might have them all figured by now, but I have no way of knowing for certain, so I need help here from my fellow JP collectors)
So while you may not have much use for black mana in a mono-blue deck, you can still generate and float any color of mana with cards like Mana Confluence
I found myself largely taking out Collected Company and trimming from some of the 4 ofs to make room for Fatal Push, Assassins Trophy, etc
If youre going all in on Greven, you probably want the Whispersilk Cloak / Lightning Greaves / Rogues Passage suite to make sure you get him through
