Osgood, Operation Double

When you cast this spell, create a token that's a copy of it, except it isn't legendary.

T: Add C. Spend this mana only to cast an artifact spell or activate an ability of an artifact.

Paradox — Whenever you cast a spell from anywhere other than your hand, investigate. (Create a Clue token. It's an artifact with "2, Sacrifice this token: Draw a card.")
