I have a bunch of unis with either regen, counterstrike or fragrance and unicorns here, too (also never managened yet to breed more than 2 of them on one uni at most). if you want to combine - feel free to check them out. they are staying in the sales tab and in the tab "Uni GP1+2 standard": it contains Debby for example (GP2) with Fragrance and Svenja (GP1) with counterattack. (I don't research genes below GP3 but their behaviour in the arena gives good hints. Unis having these genes are marked in their name). Plus there are a couple o GP3 Regen unis that are standing in the sales tab and will soon be available for sale. (Careful though: there is one GP3 uni marked with [RCA] but he has only counterattack, regen is recessive. but he has researched genes as a GP3, so this error is visible. I marked him with R by accident and did not use an amnesia on him yet.)
Some further unis with Magic Horn and/or Fragrance are not for sale but accept breeding offers: check out the tab "Uni GP1-2 [MH][F][CA]" for those.
I shot the thread but I didn't shoot the TO
