The Keeper of Kaldra (Unknown Event RZ03c) - Rare Magic: The Gathering Card

When The Keeper of Kaldra enters the battlefield, if it's the first time this ability has resolved this game, add Helm of Kaldra, Shield of Kaldra, and Sword of Kaldra as your companions. (You can pay to put one into your hand from outside the game, once each. Use tokens to represent those cards.)
Creatures you control named Kaldra have hexproof.
