Rubblebelt Patrol

When Rubblebelt Patrol enters the battlefield, put
a +1/+1 counter on target creature you control.
Each creature you control with a +1/+1 counter
on it has "Spells your opponents cast that target
this creature cost {1} more to cast."

The Rubblebelt was once a lawless wasteland few
dared to inhabit. The introduction of the Guard took
care of the lawless part.
