Ascendant Acolyte enters the battlefield with a +1/+1 counter on it for each +1/+1 counter among other creatures you control.
At the beginning of your upkeep, double the number of +1/+1 counters on Ascendant Acolyte.
If Ascendant Acolyte is entering the battlefield at the same time as other creatures, it doesn't count any counters those other creatures would enter the battlefield with.
