Whenever Tuya Bearclaw attacks, it gets +X/+X until end of turn, where X is the greatest power among other creatures you control.

The value of X is calculated as Tuya Bearclaw's ability resolves. If you control no other creatures at that time or if the greatest power among other creatures you control is 0 or less, X will be 0.

Once the ability resolves and the bonus is applied, that bonus won't change, even if the greatest power among other creatures you control does.
