Outstanding Dog Mary →Used Deck

When did this card come out!?
A card that returns to the bottom of the deck when sent to GY or searches for 《Great Dog Maron》
If it's Lightsworn or something like that, it seems like they'll let these go and prevent the deck from running out.
And maybe this is the past appearance of the bone dog sitting on Wightprincess 's lap! ? I thought
Nearby is a bone-formed 《Great Dog Maron》, or even 《Skull Dog Marron》, so I think the possibility is huge!
By all means, we believe that cards related to Mary will come out, and we are waiting for them!
I can't deny that he has a sad past...

Who could have predicted that in 2021 there would be a card that named Outstanding Dog Marron by name...
After all, far from being recorded in the previous TP, it's surprising that the last reprinted reference is "Outstanding Dog Marron" more than 15 years ago.
The mysterious background filled with Hatena marks is the same as Maron, and this is a light blue background for Marron with a yellow background.
Like Marron, it returns to the Deck no matter where it is sent to GY. You can choose to return to the top of the Deck while searching for Marron.
Basically, I think you'll want to use the effect that gives you the advantage of returning to the top of the Deck while searching for Marron, but that would lock the top, so you'd have to quickly find Marron for some kind of cost or release. By sending it to GY as material for Special Summon, I would like Maron to return to the Deck and shuffle the Deck.
That's why it's the job of the two to keep passing each other, but both have the feature of being able to be recruited from the Deck with Obedience Schooled. By sending the card to GY, you can save money in terms of hand-advertising.
While all stats are the same and effectively almost superior to Maron, I have a good impression that Maron's presence is indispensable for demonstrating true power, so I wonder if it is a practical card. Put aside for now, I really like the card design, including the illustration.
