Level up your Units quickly -- A Guide for new Rivals Players

A recurring question from new Rivals players is: "What should I do to maximize my progress in levelling up units?"

What you should do:

1. Log in daily. There is a daily reward for this, and you get get hundreds of free Diamonds each month if you don't break your streak of daily logins. 
2. Do your bounties every day. This gives you thousands of credits each day, and you can often get your bounties done within just 10 games. You can spend fuel (a free resource gained from playing) to "reroll" your bounties (small arrow next to the open bounties). This ensures that you can do the bounties while playing your favorite decks rather than being forced.
3. Use your daily free "Cloning Chambler". To ensure the Cloning Lab is maxed, you need to play 12 games per day (less than an hour) so that it's free again once the 24h-timer resets. Further down, some tipps on what units you should use your Cloning Lab for.
4. Join an alliance to request donations. You can request donations 3 times a day, and the donator gets credits and experience for donating cards. If you don't have an alliance, look for an active one on the Rivals Subreddit or on the official Rivals Discord.
5. Request your Crates and rush them with fuel. In theory, you can do this every 3 hours. But don't spend Diamonds to rush them faster.
6. Use your Diamonds wisely. You get hundreds of Diamonds for free each month. Ideally, spend your Diamonds only on Events if and when you reach a good result. More on this further down.

What you should not do:

• Don't buy the promo offers. If you want to spend money, buy Diamonds at a the best rate in the shop, and spend them wisely on Events.
• Don't spend Diamonds to rush chests, open the vault, buy crates. Spend them efficiently for the right events.

How to best use the free daily Cloning Chamber:

• It's most efficient to use it on Common Cards
• So use it on core common cards you believe will play regularly in a number of different decks
• If you don't know what to use it on, I recommend Riflemen or Wardogs, Militants or Cyberwheel, Scorpion Tank. But ensure that you actually use the unit(s).
• It can be prudent to focus on one key unit. If you always play Scoprion Tank and Militants with Nod, you might want to focus on them a lot. If you play a lot of different units, maybe use the Cloning Lab to speed up levelling up the next unit you currently use.

How to spend your Diamonds:

• As mentioned above, spending Diamonds on Events is most efficient. 
• Your rewards will depend on the Event and on your Result. 
• Basically all Events will be better than spending your money on something else, even if you manage only a 5-5 or 6-4 score in the event. But of course, it might be worth to wait for a good score on a good event before you spend your Diamonds. Especially as you can spend your Diamonds multiple times on the same event. So if you get a great run at a great event, you can spend up to 6,000 Diamonds at once.
• Among the best events are the Resource Event premium track. Crate Event standard track (i.e. rerunning this event if/when you get a 10-0 run), Champions premium track and Showdown premium track. The latter has the upside that you can rerun the event for credits, so you can rerun often until you get a good result.
• The one arguable alternative to spending Diamonds on is Cloning Chambers in the shop. This can make sense if you cannot get decent results in Events
• If you're not sure if an event is good, just ask on the Rivals Subreddit or on the official Rivals Discord
