  1. Added701.25fDetails
    If an activated or triggered ability of a permanent that isn’t a delayed triggered ability of that permanent tries to transform it, the permanent transforms only if it hasn’t transformed since the ability was put onto the stack. If a delayed triggered ability of a permanent tries to transform that permanent, the permanent transforms only if it hasn’t transformed since that delayed triggered ability was created. In either case, if the permanent has already transformed, the instruction to transform is ignored. This is a change from previous rules.

    If an activated or triggered ability of a permanent that isn't a delayed triggered ability of that permanent tries to transform it, the permanent transformsdoes so only if it hasn't transformed or converted since the ability was put onto the stack. If a delayed triggered ability of a permanent tries to transform that permanent, the permanent transformsdoes so only if it hasn't transformed or converted since that delayed triggered ability was created. In eitherboth casecases, if the permanent has already transformed or converted, thean instruction to transformdo either is ignored.
