My Battle rule for the day is Reverse Speed
Reverse speed: Slower monsters attack first. Try to pick monsters with speeds of 1. Speed affects how soon your monster will attack in battle and how effective it is at evading attacks. So a monster with a speed of 1 would normally attack last now will attack first. A speed of 1 will also have the best chance of dodging if paired with evading and flying as well.
