Thurisaz, Steadfast Defence

Runic Presence — You may reveal this card from
your hand any time you could cast a sorcery. If
you do, you get an emblem with "Whenever one
or more creatures attacks you or a planeswalker
you control, you gain 1 life." until you reveal
another card with Runic Presence.
At the beginning of each end step, you gain 3 life
if you lost life this turn.
