Luke Skywalker

Lifelink, vigilance
Whenever another creature enters the battlefield
under your control, put a +1/+1 counter on
Luke Skywalker.
Remove all +1/+1 counters from Luke
Skywalker: Luke Skywalker gains hexproof until
end of turn. Activate this ability only if at least
one +1/+1 counter is removed this way.
