While some players view these tasks as tedious chores, they are absolutely the most efficient way to build your account's wealth.

A player who plays for twenty minutes daily, focusing purely on quests, will outpace a player who grinds ladder for hours but ignores the tasks.
Managing Your Chest Cycle
You should always be unlocking a chest, twenty-four hours a day, seven days a week.

Save the massive, eight-hour or twelve-hour magical chests to unlock right before you go to sleep at night.

These quests might require you to play a specific number of spells, win games with a certain faction, or deal a set amount of damage.

If a quest requires you to play 50 goblin cards, build a deck entirely out of cheap goblins, jump into a casual match, and just spam them at the bridge.
Quest TypeThe TrickSpell UsageBuild a deck of 8 spells, enter a casual 2v2 match, and spam them on the enemy king tower; takes one minuteSpecific Unit WinSwap the card into your main deck if it fits; otherwise, reroll the quest to avoid losing ladder rank Consistency Beats Intensity
Logging in for fifteen minutes every single day is vastly superior to playing for ten hours once a month.

The developers want you to play daily, so they are practically throwing free resources at you if you know where to look.
