Frist strike, vigilance

Fus Ro Dah-{1}{r},Target creature can't block this
turn. If that creature is a Dragon, it deals damage
equal to its power to its controller.
Thu’um Mastery-Whenever Dovahkiin, The Dragonborn, deals combat damage to a player, you
may cast an instant or sorcery card from your
graveyard without paying its mana cost. If a spell
cast this way would be put into your graveyard,
exile it instead.
