Props to Popotito for their great open run. It inspired me to work on an Eccentric Officer combo deck, but so much investment goes into keeping a low cost average and getting combo pieces together, so I really wanted to find a way to immediately win the game when going off.
With that in mind, Kairos + First Flame = Profit
Deck goes off turn 5-6 most of the time. But, it is not the easiest to play.
Start with Eccentric officer. Get Kairos with Reweave or Plea for Aid (as a backup), follow it up with First Flame for ~35-42 dmg. Start with First flame against aggressive decks if you are in a crunch.
Your influence requirements are: 2 Fire in order to play your First Flame. 1 Justice most of the time is sufficient, although you'll need 2 Justice for Plea for Aid from the market (only used as a backup way to play Kairos). 1 Primal is enough. So we only really need double influence in one color to be able to combo.
Everything in the deck is geared around keeping a very low Casting Cost average, down to the reflections that count as a 1 drop in your deck, even after you use it. Tota pioneer speeds everything up by 1-2 turns. Rujin's Choice is definitely an MVP. It allows you to see the costs of all units in your deck, and allows you to go off on turn 5 much more consistently, as you can Choice a FF on top of the deck before Reweaving. You then draw your 1cc FF and can play it on curve. Having a full cost FF in your hand is also just fine, since kairos + 5 power is enough to play the full cost FF on curve as well.
Special mention on how great it feels to Reweave a Porter into a Kairos. It's SUPER fair...
There are some potential edits depending on the decks you are facing. Swift Refusal is great if you are running into tons of hate, but I opted for torch for a bit more versatility.
P.S. Don't forget that you can Torch your own dude in order to trigger Tribute on your FF.... You know... In case that is relevant >_<
