Idea's: (Rite of Replication)

Target a [[[Turntimber Ranger]]] (with just 1 ally on the battlefield): put 30 wolf tokens (each Ranger copy will see him and 4 other allies EtB, plus 5 the original creature sees) and each Ranger will get 5 +1/+1 counters.

or [[[Halimar Excavator]]] (with just 1 ally on the battlefield): mill 180 cards (each copy and the original creature will see 6 allies on the battlefield).
