Just building Merfae for casual fun, seeing how well the archetype might hold up. The deck does seem to get a fair number of interactions up on the opponent's turn, but struggles to actually close games. Then again, with Merfae Hide-and-Seek the deck has a really solid plan to win in the grind-game. I feel like the deck would struggle at the competitive level, largely because of the timer, but also because it's weak, and also highly skill-intensive to pilot, since your plays happen on your opponent's turn. You have to finish setting up while they're setting up, and then know when to do everything to get the most value and that also means understanding your opponent's deck. So if that sounds like your kind of game plan, you could probably pilot it to moderate success. They ARE cute AF tho, and stronger in practice than they look on paper.
