Strategy
Please don't read this if you like challenges and want to find out your own way to complete the level.

A possible way to beat this is by only using Pidgey and Geodude. Geodude can block alot of hits but is too slow to make it through, Pidgey on the other hand is very fast but also very weak, but he is immune to geodude's magnitude attack. first send in a Geodude, wait for it to start being attacked, then send your Pidgey. it will not get hit by Pikachu, and it won't get damage from Geodude. Wait for both to die, and then repeat. Remember: you don't get only one use per pokemon but 120 energy, meaning that, because each pokemon cost 20 energy, you can spawn any pokemon 6 times, or 2 different pokemon 3 times.

Please note that this is how I finished the level and it may not work for you if you do something a tiny bit different, because challenge levels are designed to be hard and even a perfect strategy might not be enough to win every time.
