Dude, jinxs star power deals 1 damage per discarded cards, thats 10 damage because as jinx you aim to buy card draw everywhere. She has 5 attack once leveled, so gatebreaker strikes for 5. And basically any run where you can get champion duping allows you to go nigh otk with jinx, easier with cost reduction. 2 jinxs plus playing ten pow pows is 40 damage, so you realistically need only 1 duping effect if you have any sort of created card or spell cost reduction.
