mtg cards like painter's servant All cards that arent on the battlefield Painter's Servant (EX)

Demonic Tutor is by far the most iconic and most reliable of the lot, not subject to deck shuffling shenanigans like Vampiric Tutor

This is a very aggressive ability that wants the player to attack as much as possible and to cast spells/activate abilities during combat

If you are able to hit a non-creature spell from the spells you steal from your opponents, you can reset Etali to get even more cards

If Fairy Godmother would not be in the pack, then I would take Rabbit - Reluctant Host or Virina - Fang Chief

Ringwraiths Ringwraiths is a decently strong creature, and its ETB effect can serve as a form of removal for some nice added value
