The "legend rule" doesn't apply to permanents you control. Each legendary creature you control gets +1/+1. Each nontoken creature you control gets +1/+1 for each other creature you control with the same name as that creature.

Spells and abilities your opponents control can't cause their controller to search their library. −1: Target player mills four cards. Then exile each opponent's graveyard.

As B.O.B. enters the battlefield, create four 1/1 blue Beeble creature tokens. The number of loyalty counters on B.O.B. is equal to the number of Beebles you control. (Create or sacrifice Beebles whenever B.O.B. gains or loses loyalty.) +1: Up to X target Beebles can't be blocked this turn, where X is the number of cards in your hand. −1: Draw a card.
