Makhulu, Majesty of Voice

Flying
When Makhulu enters the battlefield, choose target opponent. That player plays with their hand revealed for as long as Makhulu, Majesty of Voice is on the battlefield.
Whenever that player draws a card, you gain 2 life if it is a nonland card and they lose 2 life if it is a land card. (this effect only happens if the first effect resolves.)
