The secret of my success

The secret of my success is pretty simple. Win as many trophies as possible. To do this effectively, we artificially keep our hero cards at the lowest possible level. This does three things: (1) it reduces the cost of each tournament match, and (2) it limits your opponents to decks of the same level, which makes them easier to beat (though your own deck is pretty weak to begin with), and (3) unfortunately, it also limits the number of trophies you can win per match to four trophies (plus four additional trophies for the winning streak).

Most players level up their heroes as high as possible. This gives them a maximum of 45 hearts that they can store up, but matches cost 9 hearts and 1000 coins to play. Occasionally, you'll get matched up with someone for a maximum for 10 trophies (plus 4 additional trophies for the winning streak), but you'll have to spend a lot of coins to find those matches. But let's say you do. That means you can play 5 games per day -- hearts recharge at 1 per 15 minutes, but matches cost 9 hearts -- which limits your winnings to 12 trophies per match, or 70 trophies per day.

However, if you keep all your heroes down at level 3 only, it will cost only 1 heart per match to play, and each match will cost 75 coins. Hearts still recharge at the same rate, so you can play 96 matches for 4 trophies each win (plus 4 additional trophies for the winning streak), giving you a grand total of 768 trophies per day. That's more than three times the number of trophies you can win had you leveled up your heroes to the maximum.

But there are many downsides to this strategy.

First of all, if you've already leveled up your heroes, there's no way to level back down. You'll have to restart your game and lose all your progress and awesome cards you've already acquired.

Secondly, you can't play too many quests, or else your heroes will level up. If your heroes level up, the heart cost to play each match will increase. Once a single one of your heroes levels up to level 4, your heart cost goes up to 2 hearts per match. This effectively reduces the number of matches you can play per day to 48, giving you a grand total of 384 trophies per day. Plus, your match cost will increase to 100 coin.

The inability to play quests will limit your ability to acquire new cards from quests. The only way you can obtain new cards is by purchasing them.

You also can't play things like the Daily Dungeons of Doom. Doing so also increases your hero's experience, thereby increasing the level.

And finally, yes, there are ways to cheat in Card Wars, but I don't recommend it. Cheating is not cool. Don't do it. Yes, there are glitches you can take advantage of, but that's cheating. You can also hack the game files, but that's cheating, too. Don't cheat. It takes the challenge and fun out of the game.
