Pigging Out is a fantastic card in my opinion. I wasn't convinced until I played it. With the additional bullet and value reduction it really becomes easy to set up big combos.
When combined with the Shotgun-Longwei Fu, who can play 5 Zhu Bajie cards in one shootout play, this can ace even value 9 dudes with relative ease if your discard pile is full enough. Shotgun-Longwei Fu can get 4 or 5 bullets while he gets the opponent 9 dude down to a value of 3 or A. Then ace that dude and still profit from your higher Zhu Bajie bullets throughout the rest of the shootout. That's impressive!
In addition to that, the finishing move Zhu's Reward can become even more devastating because of the higher value reductions from Raking Dragons.
The 6-club alternative Faster on the Draw (which has similar effects to Zhu's Ferocity) is less good for Zhu Bajie decks in 95% of the cases. Unless you are playing Deputies or your Kung Fu pulls aren't reliable, the only advantage that Faster on The Draw has is that it requires only one shootout play for it to work effectively, whereas Pigging Out requires two shootout plays.
What Pigging Out most of the time did for me in my Kung Fu deck so far:
- Put more Kung Fu cards in my discard pile for Combo purposes
- Give me one Zhu Bajie card into my hand for sure
- Make my Zhu Bajie cards more powerful
- Make my Zhu Bajie combos much easier to pull off
That's a lot of benefits for one card.
The only real downside Pigging Out has is that sometimes by discarding the top 5 cards this will result in having to re-shuffle the deck, thus making Pigging Out not worth playing in that situation. Then however I would consider not going into the shootout in the first place and wait for another turn.
Conclusion: If you're playing Zhu Bajie Techniques in your deck then definitely give Pigging Out a try. I put 4 copies of it in my deck and love it everytime time I draw it, as it gets me ready to go for my next shootout.
