Biomancer's Laboratory

At the beginning of your upkeep, put a +1/+1 counter on target creature you control.
Creatures you control with one or more +1/+1 counters on it are Mutants in addition to their other types.
Biodiversity - As long as five or more creature types are represented among creatures you control, mutants you control get +1/+1 for each +1/+1 counter on them.
