There are already videos of Megalith being a good rank 4 Xyz deck. This card will give them a non destruction removal.
Blackcorn Ship: But I only have 2100 Atk
Megalith Phaleg: I got your back, lets send that sunsaga to the graveyard wihout destroying it.
oh come on off course a lot of deck have many backrow but this guy's idea is actually legit. Why do some people always want to in contrary. This guys giving you a good idea. Megalith Phaleg Can easily increase this monsters atk making its effect range much wider. If you think like that might as well not play sunsaga cause there are three backrow.
Sorry mate but I can't do that right now. Anyway I think there are videos on YT that uses megalith Xyz variant. Basically use the trap that revives megalith in the grave. It has a condition that the monster it revives return to bottom of deck ones they leave the feild but if you use them as Xyz material you can just send them back to the grave.
