Was this deck:

...the top placing Tennin deck at Worlds this year? Absolutely.

...undefeated after the cut to day 2? You better believe it.

...the top placing Mutate deck at Worlds this year? I can't say for certain but let's be real: YES.

Through a combination of extremely good piloting, the raw power of this unstoppable juggernaut, and an equally well-constructed Omar Keung: Conspiracy Theorist list, I managed to end the first day with 12 prestige. That's 4 entire wins with only two decks. Thanks to good tie breakers, that was enough to secure my place in the top 213.

Tennin is a tricky ability to build around because it says different things against different players. In some games, the ability says:

"When your turn begins, you may place 1 advancement token on a card if the Runner did not make a successful run during his or her last turn."

but in other games, it says:

"The runner loses their mind and will stop at nothing to get a successful run each turn. Doesn't matter what you installed, what they installed, what's going on. They will always run."

Usually, the more experienced the player is, the more Tennin says the second thing.

But how to take advantage of a runner who Always Be Running? The answer is obvious... get them to run into Pop-up Windows, rez the Pop-up Windows, then turn the Pop-up Windows into ridiculous inconvenient ICE using Heritage Committee-Mutate combos.

Here are some amazing things that happened:

I turned a sickened, diseased, parasited Wall of Static into a healthy Wall of Thorns, locking the runner out giving me a GAME WIN.

I won another game WITH THIS SAME DECK.

I scored out a Nisei MK II a few times.

I think I won more than one Psi game but I might be misremembering that.

I know I am undertaking a big risk here revealing the secrets within my amazing Tennin deck. I hate playing Celebrity Gift and prefer to have terrible economy rather than revealing precious secrets. But I know how glum you are all feeling in this post-Worlds CtM/Sync/Whizzard meta and I thought you could use some help with this fresh list.

Further, it is my earnest hope that the Netrunner community would start to regard me as one of the premier Mutate deckbuilders of our time.

Thank you.
