Leovold, Emissary of Trest

If you and a permanent you control each become the target of the same spell or ability an opponent controls, Leovold’s ability will trigger twice. The same is true if two permanents you control become the target of the same spell or ability an opponent controls.

Leovold will “see” cards drawn by opponents earlier in the turn before it entered the battlefield, although Leovold can’t affect cards drawn before it entered the battlefield. For example, if an opponent draws two cards, then Leovold enters the battlefield, that opponent can’t draw more cards that turn, but the two drawn cards are unaffected.

Replacement effects (such as that of dredge or Laboratory Maniac’s ability) can’t be used to replace draws that Leovold disallows. However, if an opponent’s first draw is replaced (by a dredge ability, for example), that draw didn’t happen and Leovold won’t stop the next draw.
