This deck should be relatively straightforward to use, and all of the cards, I believe, come from either the Syndicate reward tree or the Syndicate starter pack.

1) Vivaldi Bank can be used to gain coins and fish for a card that you desperately need to play right now.

2) Saint Gregory - personally, I prefer playing this card before it evolves, but to each their own.

3) Jacques should be kept until the last round, unless you desperately need a winning hand. It is probably also best not to boost him with coins above 8, unless you are absolutely certain the opponent is unlikely to play something like Geralt that will take him out entirely.

4) Ulrich is a great card for duplicating something in your hand or for giving an Eternal Fire Disciple that much-needed boost that will keep him alive longer.

5) Lieutenant von Herst - another amazing card, as it auto-generates Firesworn Zealots (if you have a cleric present on the board), while also having an ability to evolve them to Flaming Rose Footmen. Probably best to keep it on a different row from your Eternal Fire Disciple.

6) Procession of Penance - decent card. Also a good play before Jacques, if you want to check whether or not the opponent has cards like Geralt that can take out high-power units. Because they are likely to get baited by Procession. Keep in mind that you need at least 5 Firesworn tokens on the board before you can play Procession at its full power.

*) The rest of the cards are for generating coins and for getting boosts from spawning Firesworns.

I have been winning relatively consistently against non-insane decks with this. This deck does, however, struggle against decks that use Reaver Hunters or some of the "continuous damage" Witcher cards, such as Cat Witcher.
