I've been thinking about what the oracle said, and I am pretty sure that marina is MY best option over alexei. Lets think about some situations:
Roots, GHEIST, and other stops like wendel, qubik, bogdan, bryan : Marina has one more power, no deal for alexei.
Sob clans with power reducing are better for alexei, edwin and tula are easy targets. Buf if you plan to bluff, marina can really take damage down.
Skeelz are still making fun of alexei either.
Power protection cards can also be matched by alexei, but only melanie is not afraid of marina dmg reduction, while heitachi will not always want to fight for "only" 4 life gap.
+- life dudes: moses, ector are very efective against marina, but lots of others have more than 4 damage (like diana), so its not really a worry.
Nakata, karen, flinch and other stops are just waiting for alexei to play first. With only one SOA, its easy to avoid, but you still dont want to be threatened.
Putting in the balance, having only one defeat card, i just preffer marina, 'cause there are more situations where she is better, but its personal. Losing 1 power to come with a totally different ability, with totally different weak and strong spots is really players choice. Thanks for the sugestion, anyway.
I don't think SoA is necessary in this. The typical strategy for a deck like this is to nail down an r1 win with an All-Star, ideally with 5-6 pills, less if you think you can get away with it... And threaten a 2nd or 3rd round Tsubame fork. If Tsubame is not available, landing two strong cards and relying on Marina or Kusuri should usually secure the win.
Well im not saying replace marina with alexei, and your arguments was not very strong, you are just saying all the pros of marina against alexei. what if you see a karrion getting thrown at you? cyb lhia? and its just so nice having an SoA on hand, facing something like buba otherwise would be a pain.
well I have not used tsubame before, but from what I know, all decks that do well usually have SoAs. You might have luck with this though, who knows
