[unconfirmed]Ancestor's Chosen + Oath of Druids

[Konatsu]

When Ancestor's Chosen enters the battlefield by Oath of Druids,
I believe it can recover the number of all cards that were flipped at that time.
(Even if Gaea's Blessing falls into the graveyard at the same time.)
I attached save file.

However, I cannot reproduce that play.
His ability allows me to recover only the number of cards that were originally in the graveyard.
This is a bug only for certain combinations, so if it is not too difficult, please address it.

I tested a bit but no issue for me in dev nor in savegame.
