Lionguard

While Thurion, Winter King is on the field, Lionguard gains +2/+2 to its attack/defense
values and control of Lionguard cannot change.
When Lionguard attacks, the controlling player
can pay {w}{w} so any card that attempts to defend Lionguard is tapped instead and does not defend.
Force Sense (Lionguard can defend against non-Vehicle cards with Stealth).
