Dr. Emmett Brown, Inventor

Great Scott! — When Dr. Emmett Brown enters, search your library and/or graveyard
for a card named The DeLorean Time Machine, reveal it, and put it into your hand.
If you search your library this way, shuffle.
Start your engines!
I Figured What the Hell — At the beginning of your upkeep scry X, where X is your speed.
Friends in time
