[Captain Nash]

I'm still thinking BAF will be Apocalypse. But I can't imagine we won't get a second wave, unless they take only the main characters are put them in two packs.

But for my choices:

Wave 2: BAF: Nemesis
Sabretooth
Cyclops
Bishop-- I am changing Iceman out for him because as cool (ha, pun!) as Iceman is, Bishop was pretty integral to the story as well.
Rogue
Storm
Nightcrawler
Magneto

I could see them stopping there, but like you Kylactus, I could easily build a third wave:

BAF: Abyss - I've never been a huge Sugar Man fan so I'm trading him out. Also he's a Horseman, Sugar Man is not.
Mikail Rasputin
Sinister
Iceman
Gambit
Quicksilver
Mystique
Dazzler - almost an in joke here, since we've gotten 2 Dazzlers in recent years, why not a third that looks completely different than others.

Throw in a Kitty/Colossus 2 pack and a Dead Man Wade from the Deadpool/X-Force wave and I'll be happy. Oh sure, I want Damask and Switchback too but they're a little deep cut even for this story line - which...btw...did Switchback even ever have a 616 counterpart??
