Just need to check that Put and Play are different.
Play (Verb, 404): A play is to put a hero from your hand into play, use an action or amulet card from your hand, or to use a card’s power. A player can play a non-combat action card when it is his or her turn.
Put (403.5): A hero or feature can be put into a zone. It can be put into a zone from a different zone or a different area. A hero put from one zone into another is not moved.
The reason i'm asking this is because the new Suit - Ms. Moon, Double Agent states that it can't be played in round 1 and i want to know if it is possible to use send backup to put it into a zone with a friendly suit during round 1 as it is put into a zone rather than being played.
