Flying
As an additional cost to cast artifact spells, you
may pay 2 life. If you pay life to cast a spell this
way, that spell costs {2} less to cast.
At the beginning of combat on your turn, choose target artifact creature or vehicle you control.
Until end of turn, that permanent gets +2/+2
and gains your choice of flying, lifelink,
deathtouch, haste, or trample.
