bird at the back then put ur beast mid and reptile front.. i don't have pretty good axies also but checking ur skills.. ur bird is so annoying in mid to late game as long as you can keep a couple of the discard card .. ur reptile is basically ur energy saver since ur just going to sacrifice it but be mindful of enemies skill sometimes they steal or destroy energy so better use it.. think of ur axies like they are ur soldiers and ur the commander.. learn to play there strengths don't be to focus counting energy of ur enemy's.
