Odin's Helm

When Odin's Helm enters the battlefield,
you gain 5 life.
Planeswalkers you control enter the battlefield
with two additional loyalty counters.
You may spend mana as though it were mana
of any color to cast planeswalker spells.
Sacrifice Odin's Helm:
Prevent all damage that would be dealt to
target Planeswalker until end of turn.
