help with legion skill

[chrisporo]

Hi, first post on vanguard area its a simple question.

The legion skill in brackets is as follow: (If your opponent's vanguard is grade 3 or greater, this unit may return four cards from your drop zone into your deck once, search your deck for the specified card, and Legion)

The legion skill says "this unit may return" i was wondering since it says may then does that mean you have to return to activate the legion or you can choose to return and activate either way.

Thanks for the help

The use of "may" simply means that returning is optional but if you don't return you can't legion. To put it differently "may" only means that you don't have to return as soon as you have 4 in drop and both players have g3 vanguards but rather you can choose when you perform legion.
