Text:

你施放的无色咒语减少来施放。
+1：面朝下地放逐你的牌库顶牌并检视之。派出一个2/2无色精怪衍生生物。当该衍生物离开战场时，将所放逐的牌置于你手上。
−3：消灭目标有色的永久物。

Rulings:

• 5/3/2019 To determine the total cost of a spell, start with the mana cost or alternative cost you’re paying, add any cost increases, then apply any cost reductions (such as that of Ugin). The converted mana cost of the spell remains unchanged, no matter what the total cost to cast it was.
• 5/3/2019 A colorless spell whose mana cost is <img src="/Handlers/Image.ashx?size=small&amp;name=2&amp;type=symbol" alt="2" align="absbottom" /> or <img src="/Handlers/Image.ashx?size=small&amp;name=1&amp;type=symbol" alt="1" align="absbottom" /> will cost <img src="/Handlers/Image.ashx?size=small&amp;name=0&amp;type=symbol" alt="0" align="absbottom" /> to cast.
• 5/3/2019 Once you look at the exiled face-down card once, you may look at it again any time you wish. If another player gains control of the Spirit token, that player can’t look at the exiled card.
• 5/3/2019 If the Spirit leaves the battlefield for any reason, you’ll put the exiled card into your hand, even if Ugin left the battlefield before that happened.
• 5/3/2019 If you’ve activated Ugin’s ability multiple times, you must keep track of which exiled card belongs to each Spirit token.
• 5/3/2019 If an effect such as that of Doubling Season causes Ugin to create two Spirit tokens, you still only exile one card from your library. You’ll put that card into your hand the first time that either of the tokens leaves the battlefield.
• 5/3/2019 A land normally has no color, even if it can produce one or more colors of mana.
