John Constantine, Hellblazer

You may reveal the first card you draw each turn
as you draw it. Whenever you reveal an instant or sorcery card this way, create Demon Constantine, a legendary 4/4 black Demon creature token with flying.

Whenever John Constantine, Hellblazer deals combat damage to a player, investigate that many times. (Create a Clue token. It's an artifact with
"{2}, Sacrifice this artifact: Draw a card.")
