Bug: Blade of Shared Souls/Ratadrabik of Urborg combo summoning tokens the wrong creature.

The token copy that Ratadrabik makes when you do the Blade of Shared Souls, copy a legendary creature, the thing attached to the blade to the legend rule line of play, is what the Blade of Shared Souls originally attached to rather than what Blade of Shared Souls turned the creature into.

Example:
Play Blade of Shared Souls with a Ratadrabik on field. For Mirrodin! summons a Rebel token and auto attached the Blade. Blade trigger to copy happens and you choose Ratadrabik. Now there are 2 Ratadrabiks and legend rule comes into effect. You sac the Ratadribik attached to the Blade to Legend Rule, trigger the ability on the Ratadrabik on the board.

On X-Mage, this will give you a 2/2 Rebel token with Vigilance.
On MTGA (and I'm assuming Paper since it hasn't been changed yet) You would get a non-legendary token copy of Ratadrabik

No files or tests are identified. Reproduce the Blade of Shared Souls and Ratadrabik of Urborg interaction described in the issue, then trace how the copied creature and legend-rule trigger are resolved. Done means the resulting token copies the creature after Blade transforms it, rather than the creature originally attached to Blade.
