Steps

1. 1Cast Synth Infiltrator by paying its mana cost. Choose to have it enter as a copy of Princess Yue.
2. 2Put Synth Infiltrator into your graveyard due to the legend rule.
3. 3When Synth Infiltrator dies, it triggers, returning it from your graveyard to the battlefield as a land named Moon. Choose to have it enter as a copy of Astral Dragon, gaining its abilities.
4. 4When Synth Infiltrator enters, it triggers, creating two token copies of itself, thus creating two copies of Moon with Astral Dragon's abilities, that are 3/3 Dragon creatures in addition to its other types.
5. 5Put all but one of the [[clones]] into your graveyard due to the legend rule.
6. 6The Synth Infiltrator tokens each trigger. Resolve a trigger, creating two token copies of itself, thus creating two copies of Moon with Astral Dragon's abilities, that are 3/3 Dragon creatures in addition to its other types.
7. 7Repeat from step 5.
