In any card-based competitive strategy game, the battle is often won or lost before you even queue into a match.

Many beginners simply throw all their favorite, highest-level, or flashiest legendary cards into one deck and hope for the best.
The Essential Roles
You cannot build a deck that only attacks; you must have dedicated slots for defensive buildings, spells, and anti-air support.

If your deck has three different win conditions, it is too heavy; if it has none, you will never actually take a tower.
Examples: Hog Rider, Giant, or Miner.Spells provide guaranteed value.Always have reliable anti-air defense. The Cost of War
The average elixir cost of your deck dictates exactly how fast you can play cards and cycle back to your win condition.

If it is too light, you will lack the raw damage required to break through a heavily fortified defensive position.

If you consistently lose to air decks, swap a ground melee unit for another ranged anti-air attacker.

Deck building is an iterative, constantly evolving process that requires patience and an understanding of the current meta.
