Blade Master

What's the best unit to counter Blade Master?

Spectre Possibly. It will only take 200 damage from him everytime.

Or put cards out with low Armor Number that is also Heavy or Enchanted type.

Duke Vamp in my opinion - endures minimum damage and inflicts maximum damage (based on armor types).

Blade master is only strong against a handful of cards (e.g., Gargoyle). Otherwise it can be relatively weak, my Aphrodite is much stronger.

If it is hitting you real hard, the best answer is Blade Shield.
