Upgrade the TERROR CRY.The torso(if you wanna keep it, please do, it goes to mythical),otherwise, change it to BRUTALITY or WINDIGO. Upgrade your legs, pray for ROLLING BEASTS and THE CLAW to drop.remove HEADHUNTER and ARNOLD.
Pray for ANNIHILATION and NIGHTFALL to drop.If you have it, use it. remove a RAPID DESTRUCTION and add a NIGHT EAGLE.
If comfortable with HURLBAT keep it, but use VOID preferably.
Pray, pray and keep praying for HEAT ENGINES,ENERGY ENGINES,COOLING MASS BOOSTERS,ENERGY MASS BOOSTERS,and PLATINUM PLATINGS.
At your level dont use epics to upgrade, and at any level, NEVER use legendaries to upgrade.Dont buy more than 30 boxes a day, keep winning in arena.
If out of slots for storage don’t worry, they will be stored in the unclaimed boxes section.
cheers, and good luck.
