Magni, Dwarven King

At the beginning of your endstep, untap up
to two Dwarves you control.
Impenetrable fortress - when a creature attacking
you is blocked by a Dwarf, that creature gets
-2/-0 until end of turn.
Spoils of War - When a creature attacking you
dies, if it was blocked by more than one Dwarf,
draw a card. This triggers only once each turn.
