Theorycrafting a high value deck for whatever IronLad/Jubilee pulls while Howard/Zabu supports them, with Chavez being always on the bottom which helps.
Absorbing has solid targets, with turn 6 cheese going for IronLad & Absorbing (with Zabu).
Typical Daredevil > ProfX/Spiderman combo with IronLad as a Backup.
Obviously Cosmo kills half the fun.
IronMan/Darkhawk/Doom are definitely switchable, but with IronMan and Doom still being one of the best surprise cards ingame. Imagine the turn 6 IronLad/Absorbing into IronMan/Doom dream > potential 8 cube gainer :) (still not sure if that even works, since IronLad will probably become a Ongoing Card and Absorbing has no target :p)
Cards to consider to switch for IronMan/Darkhawk/Doom depending on the meta >> ShangChi, Infinaut, Enchantress.
With the right changes it should have a positive winrate against a couple meta decks.
I theorycrafted some more specific Howard & IronLad Decks for Galactus/Ongoing/OnReveal/Garbage/Toxic... Decks, but I liked the idea of doing all in one.
The base deck will mostly always contain Howard, IronLad, Chavez and Jubilee, since they support each other insanely good.
