All on opinion.
Jungo is perfect for life-gaining while Piranas plunder pillz.
For a more affordable price, I'd recommend Piranas, because some of the pretty decent cards are under 1000 Clinz.
Then again, there are some decent Jungo cards under 1000 Clintz too...
Yugirival, except, a fair amount of the better Piranas' cards are 10k+. Um, if you want a Smokey Cr for DTs and DMs, that's another 30k, which is more than you'd pay out for an entire good Jungo deck. Um, if you add Dalhia, that's another 16-20k before you go anywhere else.
Piranas are great for ELO, but some of their best cards are unplayable at the moment; still, there are replacements. Now people play Ector instead of Smokey Cr as Smokey Cr is banned.
