The only thing acceptable in this box is this archetype which is an absolute waste, weak in every department. In comparison Mayakashi is a top tier deck , the biggest biggest Megalith has 2500 ATK only come on what r u smoking Konami ? Its pretty clear this box has 0 potential
Any form of non-destructive disruption can easily wreck a Mayakashi deck. Just bounce/banish/shuffle the fox, and they're stuck in a stutter-step. Plus, due to the deck's reliance on summoning its four-part "parade" from the extra deck, there's little room for other options. Sure, it can be viable, against certain decks. However, it's far from top-tier.
I don't think it's had any relevant showing since BUT Megalith got first place Stage 2 in the EU KC Cup a while back. So, yeah, uh, I don't think you can say it's pretty clear the box has 0 potential anymore
