Leovold's Operative — ruling 1

You can turn more than one Leovold's Operative face down to draft additional cards from one booster pack. However, for each Leovold's Operative you turn face down, you will skip drafting a card from an additional future booster pack. For example, if you turn three Leovold's Operatives face down as you draft a card from a booster pack, you may draft three additional cards from that booster pack. You then won't draft a card from the next three booster packs you are passed (and/or open).
