OK, not fully mine.

My friend SaviorJP send me his deck some time ago, many of you have played him.

One of the best Threbin players then.

I changed up some cards so here's mine:

Hero: Threbin the Righteous (41 cards)

Ally (16):
1x Zealous Mystic
4x Zailen Scholar
3x Templar Adventist
4x Zailen Crusader
2x Devoted Knight
1x Elizabeth Winterborn
1x Justicar Alysia

Ability (18):
2x For Unaxio!
3x Strength of Conviction
4x Spirit of Devotion
3x Focused Prayer
1x Zail's Hymn
1x Banish
1x Confluence of Fate
3x Tidal Wave

Item (6):
3x Wizent's Staff
3x Rod of Smiting

Deck Code: 734116B

Notes

Confluence is your least important draw card.

Best route is to have t2 Scholar and t3 attachment. Even better, have Zailen Scholar out on t3 first, followed by attachment on Scholar.

The basic Confluence + For Unaxio! is still in this deck.

Not the easiest deck to play but if you want a good Threbin deck for April 2023 Challenge, you can use this.

During mid-game you will have to decide if you'll want to rush-win : via Rod of Smiting, or "win later" by drawing via Wizent's Staff and winning via allies.
