Ok, as you're the master perhaps you can help me out? Tell me what's so badly wrong with this deck:
ST - Brouver
Sihil
Caretaker
Geralt: Aard
Geralt
Morenn
Nirvellen
Ciaran
Iris
Lacerate
Waylay
Sapper
2 x Spear
2 x Ale
2 x Vrihedd Dragoon
2 x Sentry
2 x Mountain Elite
2 x Swordman
2 x Bowman
Decent low units, lock, row alignement/damage, artifact removal, Sihil + Caretaker.
nedders, I am not an expert, but as far as I can see, the areas in which your deck can do better:
1) Having only 3 Artifacts and Caretaker is a little riskier. I would prefer to thrown in one or two more artifacts (like Crushing Trap or Mahakan Horn or Pitfall). Otherwise, there is a big chance that your Caretaker may brick.
2) Two Ale seems too much. You have only Swordmaster and Sentry who you can unlock and both of them would most probably be killed than locked (due to low power). You can reduce at least one there.
3) Instead of BME, you can use the Dwarf who does 3 damage and boosts himself to 2. BME can brick sometimes. Say if the opponent plays W3 on the Melee row, BME is dead.
4) I would think Crushing Trap as mandatory for Movement deck. With Aard and Nivellen, it can get a good value as well as help you not brick Caretaker.
5) Shouldn't you have Vrihedd Brigade?
6) Even Waylay is a riskier card. In short R3, it can easily brick. Since you have majority of your gold card as non-elf, you can replace it with something else.
This is just an opinion from a Rank 13 player. So, I may be wrong in all my points.
