The effect of Smuggler's Surprise's last mode affects only creatures you control at the time it resolves. Creatures you begin to control later in the turn and noncreature permanents that become creatures later in the turn won't get hexproof or indestructible. However, if you chose Smuggler's Surprise's second mode, any creatures you put onto the battlefield that way will gain hexproof and indestructible until end of turn if their power is 4 or greater.
