Brain Maggot - 1B
Enchantment Creature - Insect (Uncommon)
When Brain Maggot enters the battlefield, target opponent reveals his or her hand and you choose a nonland card from it. Exile that card until Brain Maggot leaves the battlefield.
This Thoughtseize on a stick will snag your opponent's best card out of their hand while triggering your constellation cards such as Doomwake Giant and friends. As an enchantment, it'll also survive an Extinguish All Hope. Sadly, with a low toughness of one there's a pretty low chance Brain Maggot will actually live that long.
One way to abuse Brain Maggot is to sacrifice it while its "enters the battlefield" ability is on the stack, say to Barrage of Expendables, Tymaret, the Murder King, Bubbling Cauldron, Trading Post, or Korozda Guildmage. You'll reap the benefit of whatever card you sacrifice it to, and your adversary won't get the card back in their hand because it'll stay exiled forever.
