If an effect would create one or more tokens under your control, it creates twice that many of those tokens instead.
If an effect would put one or more counters on a permanent you control, it puts twice that many of those counters on that permanent instead.

Everything that is specified by the effect creating the original token or tokens will also be true about the additional token or tokens created by Doubling Season's replacement effect. For example, if an effect tells you to create a token "tapped and attacking," the additional tokens will also be tapped and attacking.

Planeswalkers will enter with double the normal number of loyalty counters. However, if you activate an ability whose cost has you put loyalty counters on a planeswalker, the number you put on isn't doubled. This is because those counters are put on as a cost, not as an effect.
