How it works
Cast Quicksilver Gargantuan by paying its mana cost. Choose to have it enter as a copy of Princess Yue.
Put Quicksilver Gargantuan into your graveyard due to the legend rule.
When Quicksilver Gargantuan 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.
When Quicksilver Gargantuan 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.
Put all but one of the Quicksilver Gargantuans into your graveyard due to the legend rule.
The Quicksilver Gargantuan 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.
