If I recall correctly the only time he ' s mentioned it is when a commercial promo thing was filmed featuring him back in 2009 . It ' s only come out recently because for some reason , YouTube has been running the old commercial lately . <| sep |> Never say never . <| sep |> 3 for Veria flax <| sep |> Crosspollination across different Cube archetypes is a very desirable criterion when evaluating Cube cards , and having Ulamog as a viable reanimation target greatly increases its maindeck percentage . This is one reason why I ' d prefer for most , if not all , the expensive colorless stuff be artifacts . Expensive artifact bomb creatures support ramp , reanimator , and the artifacts deck , which often works as a flavor of ramp andor reanimator . So for a long time , I just had a policy of Karn being the only expensive nonartifact colorless bomb at 5 mana . Note that my cube is unpowered , and while there ' s plenty of powerfulbroken interactions , I ' ve also trimmed away some cards that I think are a bit narrow , like Channel . But Ulamog made it in for a bit , although he was replaced by Emrakul who is easier to hard cast , and probably ends the game about as quickly . In the end , I feel like I have room for only one big Eldrazi . I ' ve also added a few cards like Oath of Druids that might benefit from having a couple big creatures that the artifact deck doesn ' t want .
