Laurelin and Telperion

Creatures you control have flying, double strike, vigilance, haste, hexproof, and gain +2/+2.
When Laurelin and Telperion leave the battlefield, create two colorless construct artifact tokens with "{t}: Add {2} to your mana pool."
"Yet even as hope failed, Telperion bore at last one great flower of silver, and Laurelin a single fruit of gold." - The Silmarillion
