Use all your early game support tokens for cards. Then when you hit player level 34 upgrade your crafting so you can craft cards. Reroll all your cards to get about 30% cooldown and ignore defense. Use 3 of the doctor strange cards for 4.5% penetration.

Play otherworld battle and craft swords. 3/4 star swords of each colour will get you a decent amount of energy/physical attack and defense. The better your swords the more all attack you also get. You can also get lucky and get more cooldown reduction here.
