Koaki is tier 1. i just reach kog in no time with a 80% win ratio, i've just did with a random build i made because i don't have every card (only 1 sandman lol). the only deck that really make me thought and countered me a lot (even winning me) was silent spellbook. but nothing that koaki ice can't afford (if you manage to use a hey trunade before fates).
Glad this deck is not annoying as sylvans were, I bet when people lost to those veggies they got 🔥 because they didn't like to be defeated by funny looking monsters LOL. So they raged hard. It seems like artwork matters a lot ! at least here in the west.
Same thing happened with Naturia and Wood-boy. Furries were cute though, or because most of the playerbase hate felines because they're dog lovers, like how they shove their muzzlers on Konami's 🔥
