結界
當切磋強身進戰場時,溫習。(你可以從遊戲外展示一張由你擁有的課程牌並置於你手上,或棄一張牌來抽一張牌。)
每當你攻擊時,在目標進行攻擊的生物上放置一個+1/+1指示物並重置它。
If instructed to learn, you may do nothing. Discarding a card and putting a Lesson card into your hand are both optional.
If you bring a card into the game from outside the game in a Sealed Deck or Booster Draft event, you may select only a card that is in the card pool that you built your deck from.
If you bring a card into the game from outside the game in a Constructed tournament (or a Constructed game played under tournament conditions), you may select only a card from your sideboard. In casual Constructed games, the card comes from your collection.
If a card is brought into the game from outside the game, it will stay in the game until it ends or until its owner leaves the game, whichever comes first.
