原文When resolving the first ability of Brain in a Jar, the newly-placed charge counter will be counted when determining what spells you may cast. No player may take any action between you placing the counter and choosing which spell to cast.

原文If Brain in a Jar leaves the battlefield before its first ability resolves, use the number of counters on it at the moment it left to determine what spell you may cast. That number won't change because you can't put a new counter on Brain in a Jar.
