Rigo, Spara\'s Hand

Creatures you control with power 1 or less enter the battlefield with your choice of a +1/+1 counter or a shield counter. Whenever a creature you control infiltrates a player, if its power was 1 or less, draw a card for each counter on it, then proliferate. Do this only once each turn. {flavor}“Even in the underground, someone has to stick up for the little guy.”
