Steps

1. Cast Astral Dragon by paying Reflections of Littjara triggers, copying the Astral Dragon spell
2. Resolve the copy of the Astral Dragon spell, putting one token copy of Astral Dragon onto the battlefield (note this is not "created" so it is not doubled)
3. When the Astral Dragon token enters the battlefield, it triggers itself, creating four token copies of Doubling Season that are 3/3 Dragon creatures in addition to their other types
4. Resolve the original Astral Dragon spell from step 1
5. When Astral Dragon enters the battlefield, it triggers, creating 64 token copies of Doubling Season that are 3/3 Dragon creatures in addition to their other types
