Labyrinth of Skophos

If a blocking creature is removed from combat, the creature it blocked remains blocked. Unless that creature has trample, it won't deal combat damage.

A creature removed from combat by Labyrinth of Skophos remains tapped if it was tapped.

Once creatures attack or block, they remain attacking or blocking creatures through the end of combat step unless removed from combat (by Labyrinth of Skophos or a similar effect).
