Uncontrolled Experiment

When Uncontrolled Experiment enters the battlefield, search your library and/or graveyard for a card named Dovin Baan, reveal it, and put it into your hand. If you searched your library this way, shuffle it.
Whenever a player casts a spell other than a
Dovin Planeswalker, roll a die. If the result is 1, counter that spell. If that result is 6 you gain 3 life.
