@Tranceplant I agree with your statistical analysis, however, I suspect that the actual chance is greater than 10% since I have never ever needed more than 7 or 8 tries with a 10% dragon to win a battle, even against the level 20 Champions

And the advice remains solid, if everything is a 10% chance, then use the cheapest dragon possible - a level 1 Fire. Takes 100 coins and 10 seconds to craft, and when they lose, just sell them for 10 coins. Way cheaper than paying 500 coins in the healing spring where there is often a long lineup by the end of a tourament.
