定式

万智牌机制

定式是一个出现在一个法术循环上的新关键字，赋予了它们真正的持久力。当某个特定的具定式异能的咒语第一次为你结算时，你将它放逐。从那时起，在你的每个第一行动阶段开始时，你可以施放它的一个复制品，且不需支付其法术力费用。施放这些复制品是可选项，且不论之前的复制品发生了什么，你都有机会在你接下来的每个回合中施放一个。

定式规则

A keyword ability that allows you to cast a copy of a spell at the beginning of each of your first main phases. See rule 702.192, “Paradigm.”

702.192a： Paradigm represents two spell abilities, one of which creates a delayed triggered ability. Paradigm means “If this is the first time a spell you control with this spell’s name has resolved this game, at the beginning of each of your precombat main phases for the rest of the game, create a copy of this object in exile. You may cast the copy without paying its mana cost” and “Exile this spell.” See rule 707.10.
