Just very luck based, some people can get 5 of the same early strong animal by round 2 whilst I'm hardly getting anything useful. By the time you've made a great set up your at like 2 health and then face a stupid powerful team. Sometimes you can have a great win streak then lose 3 games in a row. Just seems totally unbalanced with some people getting 50/50s by like round 7 which is obserd The games rigged
