Radiating Sluggishness

Enchanted creature gets +1/+1, first strike and
totem armor. (If enchanted creature would be
destroyed, instead remove all damage from it and
destroy this Aura.)
All creatures being blocked by the enchanted
creature lose first strike and double strike
and can't gain it again until end of turn.
Should you ever have wondered how being a snail
must feel, you now know it. Slow. Very slow.
