Lotus Sanctuary

Lotus Sanctuary can't attack or block.
Lands you control get "{t}: Sacrifice this land,
add three mana of any color to your mana pool."
Other permanents you control with "Lotus" in
the name produce twice as much mana.
"The lotus, the most sacred of flowers, must be
nurtured and treated with the utmost respect." - Etiith
Kul, Royal Lotus Tender
