Return to Ravnica new mechanics Explained (Part 4 of 5)

Scavenge
You can activate the scavenge ability of a creature card in your graveyard any time you could cast a sorcery by exiling it and paying its scavenge cost. That lets you put a number of +1/+1 counters equal to the scavenged creature's power onto a target creature.

A creature entering the battlefield with this keyword doesnt bring any extras, as it can only be used from graveyard. The best place for this mechanic is on a deck filled with creatures with scavenge and maybe some self mill. Allowing any new little creature to become big by exiling other creatures from the graveyard, seems to be fun, But do you think it has a  potential to be competitive?

On next part we'll be talking about the mechanic detain.
