MTG Combo: Leovold, Emissary of Trest + Teferi's Puzzle Box
This lock ends up making opponents never have cards in their hand.
- Have both permanents on the battlefield, lock is now enabled.
- Opponent's will draw a card as normal, and Teferi's Puzzle Box will force them to put their hand on the bottom of their library.
- Leovold prevents them from drawing a new hand from Puzzle Box's "then draw that many cards" clause.
