Когда Авен-Дозорный выходит на поле битвы, выберите одно —
• Положите один жетон +1/+1 на Авена-Дозорного.
• Верните целевое существо в руку его владельца.
If a mode requires a target and there are no legal targets available, that mode can't be chosen. You must choose another mode if able.
You choose which mode you're using as you put the ability on the stack, after the creature has entered the battlefield. Once you've chosen a mode, you can't change that mode even if the creature leaves the battlefield in response to that ability.
