2 pulls (from Boss Event prog rewards), 1 x JJ (black), 1 x HE (blue).
i was lucky enough to get 2 x Heimdall (blue) from a 10 pack while he was in packs though which was crazy lucky.
Two pulls from event rewards. One four-star and one Heimdall.

By the way you post, I had assumed you had a giant roster of champed 5*s. This is kinda enlightening. 
Good luck on completing JJ… she’s one of my WORST covered 5*s, next to Wasp. Never got lucky with her pulls! Thankfully, her free “daily login” cover is days away. 
9 pulls, 2 Heimdalls (Yellow, Blue).
Done and Done.
Ha ha, no, not at all! I should really be in 5* land by now after all these years playing but it is only since last year I even had one fully covered!
