Start with Ironclad
Ironclad is the common first choice for a reason. Its cards say what they do. You hit, you block, you repeat.
The plan stays visible while you learn how turns, energy and block fit together. That clarity is worth more than a flashy kit.
The other three
Silent uses poison, daggers and card draw to win over time. The kit is strong, but it asks you to chain effects in the right order.
Defect starts weak and scales through orbs. Its power shows up later in a run, which makes the early acts tense.
Watcher bends calm and rage into big burst turns. The reward is huge, but a mistimed card can end the run.
When to branch out
Move to Silent or Defect after you can clear an act without guessing. You will already know when to block and when to push damage.
Watcher is the sharpest tool of the four. Try it once the others feel routine, not before.
