Meddling Infiltrator

At the beginning of combat on your turn, put a
Forerunner Role token on up to two target creatures.
(Enchanted creature gets +1/+1 and has "At the beg-
-inning of your upkeep, sacrifice a Role attached to
this creature and draw a card.")

Whenever Meddling Infiltrator attacks, defending
player chooses one —
• Enchanted creatures can't be blocked this turn.
• Unenchanted creatures can't be blocked
this turn.
