Shardless Agent

Cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)

傾曳（當你施放此咒語時，從你的牌庫頂開始放逐牌，直到放逐一張費用比此咒語低的非地牌為止。你可以施放該牌，且不需支付其魔法力費用。將所放逐的牌以隨機順序置於你的牌庫底。）
