I had a small stockpile of CP and threw it at the Loki store. Got a Purple on my 4th pull.
How many for you? Did you notice?
15 pulls, 0 5*. “Working as intended”
Purple on the first pull. Sometimes it works, sometimes it doesn’t.
27 pulls, 5 5* including 2 Loki. RNG was nice to me for once (except that the 1 BB is saved from my 3/3/5 BB).
Five percent of the time, it works all the time 
Got a purple on the third pull, myself. Got a bonus hero that brought Carnage to 10 covers as well. Only 4 more 4* short of 10 covers, and two of those are at 9, and IW Widow will be at 8 after the Boss Event.
Got him on pull 6. Was really going for BB Black. Got him on 13th pull. Out of 13 pulls I got 4 5* (~30%)
1 Loki
1 of each BB
I’m out. Hoarding Latest for Okoye.
Black on the first pull, which is stupid lucky since I don’t hoard and will probably only open up a single-digit number of tokens from this store in the first place.
Got 1, on pull 2.
However, from the other pulls, I got LTs as champ rewards and 2 of those turned into 2 Okoyes I needed, and she is now champed. I’m happy.
Think I got my first Loki on the 4th pull. But I kept going, so it’s gotten a bit lost in the shuffle at this point.
40 pulls, 1 Loki, 1 BB, 3 Thor
20 pulls, zero Loki, 1 BB, 2 Thor.
Only had 76 CP, figured I’d spend what I could on the store before doing a full on hoard in the 2 weeks between now and when he enters Latest.
Got a black Loki on the first pull. Other 2 pulls were 4-stars, but still quite some luck.
I had 200 CP, so my 8 pulls gave me 1 Loki green and 1 BB green (made him 3/5/5). The rest were all champ levels for 4*s. Got 1 BH BWIW, and that combined with the covers I’ll get from the Thanos event will mean I can champ her.
20 pulls till I got a Green Loki.
Also got 3 Bolt covers (2 needed, one to save) so Bolt is up to 10 covers now.
Solid 5* return.
KGB.
19 Pulls no Loki. Got 2 Thors and 1 Black Bolt though. Still got time.
11 pulls, 1 Boltagon only 
Same for me today. My Okoye was at 1/5/5 with two saved and I managed to pick up two black covers!
Woo hoo! Now I can just hoard until Wasp is out, I suppose.
3 pulls, 1 Thor (yellow)
It’s so hard restraining myself… :# Gonna wait to get all the Right to Rule tokens and see if that nets me a Loki. If not, I’ll dip into the CP hoard… but only so far. Must preserve the hoard for Latest Three. Must… resist… urge… to… press… button!
20 pulls, 1 BB, rest 4*s
