Not A Bug Cannot combine Eye of Ugin and It that Heralds the End to cast Kozilek's Command

[varal]

I had 2 It that Heralds the End and an Eye of Ugin and couldn't cast Kozilek's Command for X=5 using Lotus Petal and Eldrazi Temple 2 mana ability. The modes chosen were exiling a creature and creating tokens.
