Squire of the Western Watch

You may have Squire of the Western Watch
enter the battlefield tapped. If you do, put a
+1/+1 counter or a first strike counter on it.
Put one of each of those counters on it instead
if you control a road or keep.
Vigilance
Patrol (If you control a road and this creature is untapped, you can tap it to block target creature
that is attacking a player other than you.)
