"Magellanica, the Deep Sea City" Rating Score by まさむね

A new "sea" that is shrewdly written as "sea". ① is his deck top operation. When using effects, Atlantean uses search and his GY Fertilize effect more often than draws, so you can decide to some extent what you want to draw on the return turn. Nonetheless, if you don't pay attention to combos, it's a good effect if you don't care about combos because you can draw in immediately even on the opponent's turn by using extra G.
② is like a single version of Lemuria. It is an effect that assists Synchro Summoning, but it is restricted to 1 turn and does not have the effect of lowering the level. However, it can also be used to adjust the level of the Black Luster Soldier, a chaotic warrior that refers to the level at the time of link summoning, to match the level at the time of Xyz summoning, and to adjust the level of monsters released for ritual summoning, although it is not known if it will be used.
I thought that 3 was just a combo with Primadona, but Peeping Handes. The condition is that he will be able to Synchro Summon the WATER monster during your Main Phase, so it may be easy for him to interfere, but if you want to go on the offensive, you should definitely aim for it.
I've said this far, but this card alone has a strong color of combo just by supporting development. If it can be activated when monsters are lined up to some extent, it seems to be quite strong, but when he is outnumbered or he can't deploy monsters at all, there will be scenes where he will rot as a deck. That said, depending on the card pool going forward, it may be possible to develop a route with this card and Mulan as the first move, with a total of 3 handicap cards.
Overall, let's use it together with Primadona. 3-card handicap doesn't seem to make a bad face.
