There are two variants of this deck that I`ve made:
1) Greedy (https://gwentup.com/decks/2388). More points, more control options but less consistency. Caldwell can be locked both with Ciaran and Morenn if you can`t maintain the highest unit on board but keep in mind that by having Caldwell in your list you can be punished by Geralt and Leo that are usually bricked in this match-up.
2) Consistent (this one). Obvious pros of this version are consistency due to amazing thinning (Volunteers and Iorveth’s Gambit) and carryover potential with Agitators. The biggest con is lack of low damage removals for thrive units.
