Notes & Combos

Just another M1 climb with Mermail. My 10th time in a row - Mermails best deck!! ❤️

List as usual, this time I tried playin' 2 Purulias which were good since you can also banish them for deep sea aria or discard them for your effects. Liked it alot.

Herold still gives me headaches, lost 6x in a row the final match for the M1 climb.

All in one a nice grind, I also saved some awesome replays for you guys. Go and check them out to see another Mermail Masterclass going second against full endboards, almost all of them with pure engine.

If there's questions feel free to ask.
