Hello! I recorded the Global Top 100 battle decks currently being used and am posting the results here. This list may help answer questions regarding which cards you should request from clanmates, purchase with gold, and ultimately include in your deck.
Elixir Collector widened its lead as the post popular card in the game and an easy, proactive play to generate an elixir advantage. Poison and Zap has held on as the killer spell combination, even with Ice Spirit providing another cheap AoE counter in over two-thirds of all top decks. The hardy, versatile Guards are now used in over half of all top decks. Diversity in Giant decks has made it more difficult to nail down the optimal decklist, yet nearly one-quarter of all top decks are running eight of the same nine cards. Mega Minion has supplanted Musketeer and Mini P.E.K.K.A as the most popular support troop for the Giant, while Prince remains on the front lines as a defining card for the archetype. With the popularity of flying troops, Bowler is now nowhere to be seen.
Miner decks have held steady at one-third of all top decks on ladder, usually in a control deck that seeks constant chip damage for the win. Inferno Tower and Princess are top control deck cards for single-target and AoE damage, respectively. Minion Horde remains a popular win condition for control decks and saw more use than the ground alternative Barbarians. Skeletons and Cannon saw some use in cycle decks that emphasize defensive play. Finally, vanilla troops like Knight and Archers saw a fair bit of play as defensive support troops.
