Deck building coach

Sometimes it's the play. Sometimes it's the deck. A deck coach tells you which.

Updated

A working deck needs a clear win condition, answers to both big tanks and swarms, a spell or two, and an elixir cost you can actually cycle. Missing any of those shows up as the same kind of loss, over and over.

Mercina rates the deck you're currently playing out of ten on those fundamentals, and gives a one-line verdict on what it is and what it lacks. The rating judges the build, not your card levels.

What usually goes wrong

  • No win conditionStrong cards without a reliable way to hit towers leave you defending forever.
  • Average cost too highA heavy deck cycles slowly, so you can't get back to your answers in time.
  • No answer to swarms or airOne gap in coverage is enough for opponents to target every match.

  • A deck rating out of ten on the home tab, with a short verdict.

  • In each match, whether the loss came from the deck or from the play.

A plan for your next match

  1. 01Name your win condition. If you can't, that's the first fix.
  2. 02Check you have an answer to a big tank, a swarm, and air.
  3. 03Change one card at a time and play a few matches before judging.

Mercina writes a plan like this from your own match, every time.

Questions

Does the deck rating account for card levels?

No. It scores the deck on fundamentals such as win condition, coverage, elixir curve and synergy, not on how levelled your cards are.

Keep improving

Skill Card cycling coach If you know what's in their hand, you know what's safe to play. Card tracking turns guesses into decisions. Deck Mega Knight coach Mega Knight is a defender that turns into a push. Played well it's a counter-push engine; played badly it's 7 elixir walking into a trap. Deck Hog Cycle coach Hog Cycle wins on speed: cheap cards, constant pressure and a Hog Rider back before the opponent's answer is. Deck Golem Beatdown coach Beatdown trades tower health early for one push the opponent can't stop. Timing is everything.
