Notes & Combos
I've been playing Tenyi and getting to KOG with them since they were released in Duel Links, so I can say that I'm pretty comfortable with my core decklist by now. However, I can also say that it has reached even greater heights with Forbidden Droplet. That card goes incredible with this deck, because your Tenyi monsters and Circle Spell activate their effects in the Graveyard. Furthermore, whenever your monster gets hit with Book of Moon, you can also send it as the cost for Droplet. You have no idea how many times I was saved thanks to that card, I'll share the replays as evidence. Also, one of this deck's greatest weakness is probably Abyss Dweller, and this card also deals with that (although I never encountered one while climbing today, which was when I started using Droplet, it carried me from Legend 3 to KOG).
