如果你操控指挥官,则你可以施放此咒语,且不需支付其法术力费用。
由你操控的生物获得不灭异能直到回合结束。
It doesn't matter whose commander you control. Any one will do. If you have two commanders, you just need to control one of them.
Once you begin casting this spell, players can't take any other actions until you're done casting it. Notably, they can't try to remove the commander you control to make you pay its cost.
