Tyranitar power-ups and the rest of my possible Mewtwo raiders

So I have these Tyranitars and am thinking about how to use my resources. Any thoughts? I've also done inventory on my other potential Mewtwo raid attackers, if anyone has any of thoughts regarding which of those are worth candy/stardust.

BlackFrancis - B/C 95.6% (S13-A15-D15) Level 33.5, 3314 CP — First one from a hatched Larvitar, all others are from raids IanMcCulloch - B/SE 91% (S12-A14-D15) Level 30, 3112 CP Lou Reed - B/C 95.6% (S15-A-15-D13) Level 20, 2087 IT/FB 88.9% (S13-A12-D15) Level 20, 2063 CP — Haven’t TM’d since I have better ones to power-up.

As candy comes in, I figure getting Lou Reed up around 30 is the most resource-efficient priority. Following that, I’m wondering if I should try to get the ones I’ve already powered-up higher (I’m level 35), or just work on getting more of my raid specimens up to 30 with good move sets even if they aren't quite as stellar IV-wise. (Candies are currently the more limited resource than stardust.)

Houndoom
1. Danzig
Snarl/Foul Play
S4/A14/D8 57.8%
2043 CP, Level 30

Lemmy
Snarl/Foul Play
S5/A7/D12 53.3%
1812 CP, Level 27

I could level No. 2 up to 30. Given the low IVs, it doesn’t seem worth pressing them above that. Outside of the fire and ice event, I haven’t caught many Houndours and only have 40 or 50 candies. My best Houndour is 82.2% level 23, so I’d need more candy to evolve and power-up that one. (Granted we might have a bit of time until Mewtwo happens.)

Scizor
Fury Cutter / X-Scissor
S15/A12/D4 68.9%
2077 CP, Level 27
(Only 3 candies, so probably easier to level-up this one a few steps than try to evolve another one. My only other is a 100IV Bullet Punch/Iron Head that’s at 30.)

Pinsir
Bug Bite / X-Scissor
15/15/15 100%
2374 CP, Level 30
(I have some others I could power-up and/or TM, or I could just boost this guy, since I won’t get any higher IVs and I have candy.)

Dragonite
Dragon Tail/Outrage
S15/A12/D12
3342, Level 36.5

Gyarados
1. RWFassbinder
Bite/Hydropump
S13/A15/D14 93.3%
3043 CP, Level 35.5

WernerHerzog
Bite/Dragon Pulse
S13/A15/D14 93.3%
3048 CP, Level 35.5

Gengar
1. Cheshire Cat
Shadow Claw / Shadow Ball
S12/A12/D0 53.3%
1957 CP, Level 28

JacobMarley
Shadow Claw / Dark Pulse
S14/A12/D14 88.9%
1691 CP, Level 23 PeterQuint
Shadow Claw/Shadow Ball
S10 /A14/D15 86.7%
1463 CP, level 20

Probably not worth using for this guy, but I’m thinking it wouldn’t be a terrible idea to line up a good level-30 Gengar or two. I also have a level-18 97.8% (S15/A15/D14) Ghastly and three good level 20s from hatches: 93.3% (S15/A12/D15), 91.1% (S13/A15/D13) and 89.9. So I could evolve and power-up those. I have 537 candies.

Umbreon
Snarl / Dark Pulse
S12/A13/D10 77.8%
1795 CP, Level 30
(I could TM this guy, but seems like he's the least useful Eveelution?)
