[Masters] Creation Bolster

There is nothing quite so satisfying as swinging for 50+ damage. This deck is designed to reliably let me do that, to great success. Bolster effects are naturally greedy enough that I decided to avoid doubling down too much, in favor of reliability & flexibility.

Bolster triggers

Ageless Knight - This deck actually makes enough armor to sometimes get the +6/+6 effect active. Mostly he's here for the armor-on-unit effect though.
Elham, Keen-Eyed - Another armor-on-unit effect, you don't want to swing with her much though. Golems come in handy late-game.
Grumbo, Tota Legend - Health-on-unit instead, he can get pretty big too.

Bolster enjoyers

Dran, Won't Back Down - Just an incredible card, I'm so happy DWD buffed Katra, the Devoted. Try not to play him unless you can either immediately bolster or play a second Dran.
Charming Steelguard - Infinite goons to block with.
Steelwarren Outfitter - A bit of extra power in case you need it. Note that there are only 4 Justice Sigils in the deck - I never found I needed more, but it does mean there's not much point to playing a second outfitter.
Furious Magniventris - Okay, not technically a bolster card, but it likes armor just as much. Also carries a bonus stun & activates bolster on play. Immediately brings Ageless Knight to a 4/4 too, which can be a neat trick.

Power stabilization

Creation Chant - Seek Power but better. Clutch invokes have saved quite a few games from power flood.
Naoki, Valiant Warrior - Amazingly flexible card. Usually I pledge her if she's in my starting hand. Almost always worth doing a one-for-one trade if you can get one, then put her exalted weapon on whichever unit can use it best. Her mastery isn't useless, but is mostly for forcing the opponent to try to kill her. Ignore the relic destruction bit, that almost never comes into play.

Too good not to include

The Creation Project - Maybe the best card in the game. Mandatory in almost all FTJ decks.
Riftfeeder Wasp - Another incredibly good card, used in almost all slow time decks. This deck lacks support for it but the wasp supports itself well enough that there's no need to worry. This is a back-up win condition.

Some utility

Torch - Kill something annoying, for cheap. What's to say?
Monarch Cloak - This can silence something dangerous, kill a weak unit, & activate bolster. Try to get a twofer here, if you can.
