Ludevic of the Krallenschool

When Ludevic of the Krallenschool enters the battlefield, return a land you control to its owner's hand.
{g}{u}: Merfolk creatures you control get +1/+1 until end of turn. Activate this ability only if you control City's Blessing.
If there's anything a merfolk hates, it's a collar - especially a Legion of Dusk collar, the symbol of their dusk legion.
