Most players eventually realize that in-game daily rewards alone can never keep up with your upgrading pace. New players aim to build basic decks quickly and get rid of early-game disadvantages. Veteran players want to perfect high-tier setups to dominate ladder matches and clan events effortlessly. Casual players dislike daily check-in quests and simply want to enjoy battles with ease. Top-ups let you skip long and repetitive resource farming, supplement your Gold and Gems as needed, save huge amounts of spare time, and focus purely on strategic battles.
