Authority Over The Shogunate

When you set this scheme in motion, if you have
a planeswalker in your hand, you may play it for
no cost until end of turn. If not, you may search your library or graveyard for a planeswalker card, reveal it, and put it into your hand. Planeswalkers you control gain 5 loyalty if your life is less than or equal to 10.
"My time is done. Tatsu. I grant you full authority over the Shogunate. Please. Do not let the empire fall." - Emperor Yoshiro
