Moment of Genius

Sacrifice a number of clue tokens you control
equal the number of knowledge counters on you.
For each clue sacrificed this way draw a card.
If your commander died this turn you may cast
this spell without paying its mana cost.
I am sometimes struck by inexplicable genius. No
doubt a natural state of being for one of my supreme intellect. Jokes aside it is mostly under stress.
