Gonti, Canny Acquisitor

Spells you cast but don't own cost {1} less to cast.
Whenever one or more creatures you control deal combat damage to a player, look at the top card of that player's library, then exile it face down. You may play that card for as long as it remains exiled, and mana of any type can be spent to cast that spell.

你施放之不由你拥有的咒语减少{1}来施放。
每当由你操控的一个或数个生物对任一牌手造成战斗伤害时，检视该牌手的牌库顶牌，然后牌面朝下地放逐它。于该牌持续放逐的时段内，你可以使用该牌，且能用任意种类的法术力来施放该咒语。
