A card like a trade-in that turns a level 6 card into a doroso. The performance itself is high, but the drawback is that there are still few decks that can use this card well.
By the way, who is that person standing? I thought it was 《Ritual Beast Tamer Elder》, but it's not that old man's level 6...

A new draw source following 《Trade-In》and 《Sacred Sword of Seven Stars》. Due to the cost of returning it to the bottom of the deck, it's hard to aim for his GY effect. Also, there are no themes that can be actively used because of the delicate level band of level 6. Needless to say, there is no future.

Level 6 limited draw sauce.
It's hard to earn ads because it has the effect of returning it to the bottom of the Deck and drawing two cards. The only thing I can think of is bringing Diabo back.
My impression is that it is harder to use than 《Trade-In》and 《Sacred Sword of Seven Stars》.

Level 6 exclusive draw source. Unlike Trade-in and Nanahoshi, this one returns to his deck bottom.
It would be best to bring back Diabo and others, but in the first place, the operation of level 6 itself is quite hard, so it's a matter of thought.

Level 6 Seven Star Train
Whether or not he can make the most of the bottom depends on his Deck.

Level 6 monster version of hand exchange card.
GY is sent and removed, and this time he can draw 2 cards from the deck on the condition that he is the bottom of the deck. Therefore, just like Train and Treasure Sword, it makes sense to use it together with Level 6, which has the merit of returning Deck.
The first thing that everyone thinks of is Diabolic Guy, but with D-HERO the only level 6 remaining is Dash Guy, so I feel like there's a possibility of a material shortage accident. The top candidate is to return a level 6 Normal Monster to his deck, and if it's necessary, it's a sacred clock that can be turned into a draw even if he returns other sacred clocks. He simply has a lot of level 6, and Hazy Flame and Vampire can't make the most of the deck bottom return, but there is a way to avoid accidents.
The card power itself is sufficiently high, and with his deck that uses level 6 a lot, he is at the level of loading immediately if the deck return works.

Level 6 card exchange card
Unlike a trade-in, the cost is returned to his deck, so basically it's not a card that can earn an advantage.
Just like 《Sacred Sword of Seven Stars》gradually fell out of Dragon Ruler, even his level 6 deck requires a certain amount of conscious construction to make the most of it.

Return the level 6 you want in the deck from your hand to his deck and draw 2.
He can Tribute Summon with only one release at level 6, so if you take into account the development power in the current card pool, it's not that bad, so honestly, it's not a convenient card to put in any of his decks.
If it's [Holy Hour] or [Advanced Ritual Art] and you want to keep vanilla in your deck, or if there are a lot of level 6 in the category [Hazy Flame] and [Vampire] as a whole, I think you can consider using it. … Oh, and 《Destiny HERO - Malicious》. It might be possible to use 6-axis magic, which is important for summoning rights.

2 draw cards for level 6.
Unlike Train and Nanahoshi, he needs to be returned to the bottom of the deck, so it seems difficult to produce direct ads.
I think it works as a lubricating oil in a deck that has level 6 monsters as its main axis.

Level 6 exclusive doroso, ruby is too cool to fall in love with.
★ Return 6 monsters to the bottom of the Deck to draw 2, train with similar effects, GY cost reduction compared to Nanahoshi, and exclusion may actually be an advantage Returning the deck to the bottom is an advantage It's hard to do, so the risk of being stopped is great, and the only thing that can convert the few deck returns into an advantage is Gigaplant, which I want to put out from Diabolic Guy or Ronfa, who will spoil if I skip it.
However, even if you subtract the cost, 2 draws are still excellent, and it contributes to reducing the accident rate of his Deck, which has a lot of accidents such as Sacred Time and Machine Angel. It can be said that it is an excellent card that can be considered for adoption.

Level 6 version of 2 draw cards with level reference.
After sending GY and then excluding him, this time he is the bottom of the deck, but I can only think of Diavo as the only person who can take advantage of the fact that he can return to the bottom of the deck.
Even so, there are no strange restrictions or disadvantages, and you can exchange cards, so it's still an excellent card.

It says to return Diabo and activate it.
I'm just grateful that he can be put back to the bottom of the deck and activate it, and I can avoid the tragedy of drawing Diabo again (here super important)
It's hard to earn ads, but you can compress the Deck for one card, so it's good that it's not wasted.
However, it can be said that it is a little weak as a draw source because it can not be said that it is possible to say that it is a trade-in.
I would like to bring back the 6-Star Dragons and Diabos that I get with 《Carboneddon》, but I don't know what to do because there aren't many of them.
If a 6 star version of Naga comes out, there might be one chance.
Monsters that enter the EX Deck from the beginning cannot be used as a cost, so you need to be careful.

A draw card with a cost of level 6 that finally came out.
GY, now that he's banished, he has to move back to the bottom of the deck, a place where it's even harder to get an add, but it's nice to be able to target cards on the field as well.
It's great as a normal doroso, but it's also delicious if it can be used as a means to deal with level 6 that you want your deck to have.

Level 6 Doroso following Train Seven Stars
I need to return it to his deck from hand or field
Because of its effect, compatibility with the PSY frame driver is outstanding.
Since the driver who came to your hand returns with a cost, you can shoot γ even on the back of this card.
It is also good to return the driver pulled out to the field and reuse it
