@jacobschuck , hobbits are good but you need to know when to send them. For example , level six. Once you reach 140 mana you start sending them and it makes it impossible to lose. Not everyone knows this though , so they will lose half the time. If you do not believe me try level this to this strategy. As long as you keep sending them it is an easy way to earn XP.
How to beat Self Experiment Challenge. Use tank with adrenaline and ricochet kill streak. Defend your intel. After a 3 kill streak run into the middle of the map before using ricochet. This will protect you so you can get the intel and get about half way back. With the right timing this is a good strategy. Recommended level 19+ To bad not many people get to see this comment...
@Pedro u used the wrong units. Dragons work , so do angel knights. Use those along with the elven titan , otherwise you base loses health every attack he makes.
