Hold on to ANY froakie with HA. There's a significantly larger chance of bringing down the HA from the Female. Better off having a female that brings down the HA than a male that almost never will with a Ditto. I might suggest making a different male of the same egg group 1st, then breed it with froakie, because an only 3IV ditto wont get you far very fast.
If I'm lucky I can go from nada to 5iv in 2-4 hours. I have a bunch of various 3iv dittos. So I destiny knot with one until I get one with 2ivs. Then I breed that one with the same ditto until 3ivs. Then with a similar ditto with like one stat different until 4ivs. At that point I either keep going, pick a diff ditto, or use a male and female 4iv to get the 5iv.
And I'm going for 31/x/31/31/31/31/31 but I can't trade until I get off work and I'll probably have it by then but I appreciate it.
