I think
Victoria deserves the #1 spot in the
La Junta 2* tier. She has decent enough stats for a 2*, but more importantly, she utterly wrecks mono SoA decks... SoA basically turns her into a 4-damage
Spyke. An easy-to-fit 2* card giving you that kind of advantage against pretty common setups is HUGE.
Oracle: I think you basically nailed the
Vortex tiers, well done! I value
Cyb Lhia a bit above
C Wing. A 2* that has 8 power, can gap for as high as 7 damage, and has pill recovery is amazing, even if SoA does turn her into a crappy wall. That min 4 is easy enough to play around -- if either you or your opponent gain life throughout the game, it is effectively reduced.
For the 5*s, I'd say
Naele is my first pick, with
Shaakarti being second... Just due to the last 6+ months of changes in the meta. Unmodified 7 power is starting to become outdated, and
Oflgn either has to be a hard fork, or connect for him to be of any use. SoA murders him as well. He used to feel a bit overpowered, but now he feels like a risky choice.
Naele forks much better, handles SoA and SoB better, and can sometimes just become a mean endgame wall. She is an extremely flexible card, despite needing Confidence to be at her best.
Shaakarti is a wildcard, with a Courage ability that you don't want to face on a 7/7 card with pill recovery... And of course, with 7/7 stats, she can sneak in a hard hit in an off-courage turn.
