Junkz got Riowdy and Lolly in the previous cycles. Look to get an idea which clan is due (or there abouts) go to the New Blood Pack, leave your mouse on it and which ever clans are not still there, well, those should be the clans.
Pussycats, Ulu Watu, Fang Pi Clang, Nightmare, and Sakrohm are the Clans that need loving. If I recall right, it was Ulu Watu and Fang Pi Clang together, then it was Sakrohm and Nightmare and I can't recall who which clan released new conscripts alongside the Pussycats. However, I reckon it will be any of those clans and that is tomorrow.
I dont think we'll have a Leader that stops Leader bonus for 4 situations a deck would fall into
1) you get that Leader and no other Leader making it useless
2)you get that and another Leader you might as well just have one Leader in this situation
3)you get that Leader and two other leaders cancelling the fourth cards bonus which would either strengthen or weaken the card dependin which would make it either too strong or too weak (ie easily abusible if played right like 2 amberes card and robb)
4) you get all leaders (which would usually only happen w/ a leder full deck or something similar) which is way too abusable
pretty much chances of them comin out with a Leader with stop Leader bonus slim to none
Well the Roots jumped in a little early (likely due to the unbanning of Pussycats cards). In pairs the order should be (roughly, I'm probably wrong in some places but I remember the twin clan banners well enough). Btw it's easy enough to check when cards were released on http://urdb.kirlad.net/index.php
In order of what should be released next (though with 6 cards per release it's likely to be 3 clans (though I still hope for 6 different clans :3 ).
Nightmare/Fang Pi Clang
@ Nightmare_CCK......that was confusing lol, I see where you mean, but I think if they made a Leader like that they'd be smart enough to exclude activating it's own bonus unless it had two leaders and whatnot. Personally I'd just like the card, dunno if anyone else would. *Calls copyrights on it* lol, j/k
