Description from wikia: The Phantom II was originally an unnamed and unarmed transport part of the Separatist navy, marshaled by the Confederacy of Independent Systems during the Clone Wars. The vessel was based on Agamar after the Super Tactical Droid General Kalani was ordered to the planet by Count Dooku.

Kalani's forces remained in the Agamar System for almost twenty years, avoiding shut down at the end of the war, until his forces were discovered by members of the Rebellion. The droid C1-10P found and restarted the shuttle while spying on several battle droids. Chopper informed Ezra Bridger of the vessel, and Ezra had the droid prepare the ship for departure. After realizing that the rebels and the droids were not each other's enemies, both parties joined together to successfully escape an Imperial assault. Once Kanan Jarrus realized the ship's potential, he decided their stolen vessel would serve as a replacement for the Phantom, which was lost at Reklam Station. The new ship was christened Phantom II.

The Phantom 2.0 from Star Wars Rebels Season 3 Episode 5 "The Last Battle"was already created by Lego as set 8036 The Separatist Shuttle. This set comes as pictured with instructions. No minifigures included.
