Thrain I, The First King

The dwarves you control have indestructible.
Thrain I, The First King's power is equal to the
number of dwarves you control and toughness is
equal to the number of mountains on the battlefield. Whenever a dwarf creature spell
enters the battlefield, if it spent red mana to cast
it, you can play an additional dwarf creature spell without spending the mana cost.
