My game play philosophy is: Decking them out in 40 turns is better than losing from turn 1 to a fail draw.
So i love reliable attack strategys combined with good ways of stopping or healing damage.
Any element that can do that suits me(there are more elements able to do that than what you would believe, and even if it cant do it on its own there is always the duo, trio or even rainbow).
I hate everything that is heavily luck dependent and try to avoid it(you wont see me playing anything less reliable than a nova bow unless i have to break my usual patterns).
