You can collect coins and gems by the following:
Collect idle rewards regularly. The treasure chest only holds up to six hours of idle rewards, so remember to collect the reward before you go to bed and when you wake up.
Use Hohenheim as your hero to pass levels to gain more coins. You should be able to get to level 5,000 with Hohenheim and a good formation. If you repeatedly fail to pass a level before level 5,000, ask for help about refining your formation. Do not take the shortcut of using a better hero.
Complete all daily quests:
Do not use all of your vouchers. Sometimes you will have a mission like "obtain 3 legendary troops," and you might not have enough coins to obtain legendary troops through lucky draws. Having spare vouchers can help in tough situations.
Do not combine troops that you don't intend to use. Again, sometimes you will have a mission like "upgrade 7 troops", so keep your options open.
If you have a daily mission such as "use an epic hero 30 times," use the hero in head hunt missions. You need to win the match and have the hero surviving at the end for it to count. Don't waste your chance on arena matches.
Claim rewards from daily missions. Don't wait until last minute because you may just forget.
Unless you plan to do in-app purchases, you should save gems to obtain heroes.
For new players, the wheel of fortune is the best way of obtain heroes. With wheel of fortune, a player can obtain a hero shard for an average cost of 2,100 gems. The wheel also allow the player to obtain useful rare/epic hero and troops.
The second best way of obtaining a legendary hero is play Card Master, where the average cost is 2,700 gems per shard.
Do not use gems to open hero chests.
Do not use gems to open super card packs. Only use vouchers for those.
Do not use gems to buy troops.
Do not use gems on temple of fusion until you have a high-level legendary hero.
The following troops are troops frequently used by top players:
Archers, Catapults
Undead Soldiers, Magic Apprentices, Goblikazes, Ice Mages, Harbingers of Fire, Ghost Assassins, Paladins
Peltasts, Brawlers
Meteor Golems, Frost Archers, Demons, Sacred Swordsmen
See troops tiers and basic forms
Common/rare troops are the backbone of most strong formation, and the best way to obtain them is through the ×30 troops purchase. On the home screen, tap the cowboy icon on the right-hand side. There you can buy 30 common/rare troops packs for 240k gems (216k if you have ᴠɪᴘ), which is the best deal.
Once you have at least 7 max-level troops for each of Undead Solider, Catapults, Magic Apprentice, and Undead Soldier, you can start loading up on epic and legendary troops.
The most economical method of getting epic/legendary troops is through 4-star troops card purchases.
The easiest way to get epic/legendary troops is through Temple of Fusion. However, it can be very costly. Players are advised to save gems for legendary heroes first.
In generally, 9-load troops are preferred over single-load troops because of higher combined attack and health points. See understanding troops stats.
Save them; you will need the troops when you do Temple of Fusion after you have a high-level legendary hero.
Do not send unused troops to trash bin; barrack capacity increases with leveling, and it is difficult to fill the barrack.
If you are a free-to-play player, it is recommended that you get either Davison or Poseidon through hero events. For questions regarding heroes, read the hero guide.
Many players use Ivan because Ivan is an affordable hero. Whereas premium heroes such as a max-level Zeus or Selene can cost US$1,000, a player can get a max-level Ivan for about US$250.
For fusion of common, rare, and epic troops, the recommended combination is 887 (two level 8 troops and one level 7 troops), 443, or 221.
For fusion of legendary troops, the recommendation is fusing two legendary troops along with one epic troops.
Check the troops tier list. Fuse D-tier troops first.
What troops you get is completely random.
Pass the first 1,000 levels as quickly as possible. After you pass level 1,000, start watching advertisement to slow down your progress and avoid hitting a block.

If you are asking the question, you know half the answer. Do not intentionally exploit bugs to give yourself an advantage. The developer will review players, both manually and through AI, regardless of your standing in arena. If you cheat and get caught, you will be sent to the cheater arena and you'll have to compete against people who are better hackers than you are.
Do not listen to people who give tips on cheating. Many of them are already in the cheater arena and are just recruiting new victims.
