Dreamstealer's Lair

Dreamstealer's Lair enters the battlefield tapped.
{t}: Add {c}
{3}, {t}: Tap target creature you control. It doesn't
untap during your next untap step. Put a +1/+1
counter on another target creature you control.
That creature gains first strike until end of turn
if the tapped creature has first strike. The same is
true for flying, menace, trample and vigilance.
