Diligent CT

Whenever a land enters the battlefield under
your control, you may put a +1/+1 counter on
Diligent CT.
Workload 3 - At the beginning of your upkeep, if Diligent CT has 3 or more +1/+1 counters on it,
remove all +1/+1 counters from it. If you do,
another target creature you control gets +1/+1
until end of turn for each counter removed
this way.
