Kin Gathering

At the beginning of each upkeep, Kin Gathering heals that player for X where X is
the number of Old Friend you control
At the end of each turn, each Devil Footman
you control gains X +0/+1 counters and deals
Y damages where Y is the number of Devil Footman you control
When people gather, they chat, share and laugh.
Depending on the person, that helps or worsen
