Teferi's Protection

Until your next turn, your life total can't change and you gain protection from everything. All permanents you control phase out.
Exile Teferi's Protection.
This shield sings the world's songs.
A world that witnessed my brief life... A world that embraced my many battles... It's a mirror that reflects all I strove to protect.
Thus, if this Noble Phantasm is activated, be it by man, army, castle, or even god, no attacker will break through.
