The oracle- I'll try not to take that to offence. Jay is one of my fav cards though, because it creates mindgames. It is just a difference in playing style I guess. Anyways, I find the Uppers quite weak without their bonus, due to their low power.
Another suggestion can be Vortex. Should you run into possibilities of KO, you can use their bonus as a safety net. (But this is not really applicable in Elo, due to the 14 life). But you can also easily gain pills by 0 pilling. I think C Wing would complement your FPC half quite well.
Rubie is not USELESS =.= ppl underestimate that 6 damage too much and wendel is way too unreliable as a source of SoA. rubie > wendel by far honestly. and harold is nothing special.
thank you debiliating. only problem with that half is that the deck kinda lacks Dr (if you do not use burt or wtv) and zhu tang is too attractive to ignore
