In Axie Arena, you need to be able to kill opponent axies. You do this with a good DPS or Damage per Second axie. Positioned in the back safely behind your tank, these axies have a high damage score or the number seen on the red sword on the move card. A good attack number is 100 or more. A pure DPS will have all 4 moves each with an attack number greater than 100. For beginners, a DPS will be a Bird, Aquatic, Beast, or a Bug. Slow plants and even reptiles will mean your attacks hit last which is usually a disadvantage. Take note, many competitive DPS axies will not be pure and will have other part moves that increase the strength of the rest of the part moves.
