I have thought about this, and unfortunately there aren't enough EAs in print to get enough legal characters. You need at least 10 EA characters from a single team, and to my knowledge only the xmen have enough EAs to fit the minimum roster.

If I've missed three teams you are my hero.

Deck building? Simple. Start with 20 one-cost army characters...

That's my way... but then again.. still working on a MM deck.. a viable one...

It starts with an idea. Like my last idea (seeing as how I haven't even played a game of VS in over a month, stupid job):

1. Thanos - 8 attacks. There goes opponent's board. Wait, there's the Gauntlet to stun the attacker. Oh nuts, Thanos readies. Do it again.

Take the minimum number of key cards to make it work, then flesh it out with characters, PT's, and locations to make it work (Gems, Cannibal Tech, Mr. Fantastic [Inhumans/F4], etc). Then fill out the curve, and voila!

Or I'll just take a random team, insert the biggest characters I can find, add pumps, and smash face. Depends on how much thinking I want to do.

Everyone knows those immigrants are coming to build the decks Americans aren't willing to build...

Anyhow, on more topical solution, my deck-building strategy:

Step 1: Have a stupid idea about some card interaction or team strategy.
(Example Case: Villains United & Kree have some good synergies.)

Step 2: Flesh out the idea to a goal point.
(EC: Press Chain to Bizarro on 5 on-it or drop Black Adam off-init)

Step 3: Put together a preliminary deck and test shuffle. Run it against some good decks once properly pre-formed.

Step 4: After (assumedly) getting my butt beat, look at what worked and what did not. Modify accordingly.

Step 5: After several iterations, determine 'winningness' factor. If it seems viable, test against a gauntlets of Tier 1 & 1.5 decks for its format. If not, return to earlier steps as needed.

Step 6: Pretend like my finalized piece of crap is actually hot, and then proceed to have it implode on me in real play. The level of play required for the implosion determines my overall success.

By this in no way depressing system, my best success has been Sin City, which actually got me to a PC before it managed to implode on me, and only because some number of pagan gods hate me. Woot!

I made some calls- the general consensus is, too much thinking, not enough blood sacrifice. Ted (the God of Remembering Who Has Range) thinks you need more fish in you diet, and Louise (the Goddess of Making Sure Your Opponent Never Draws a Tutor) really wishes you'd write. Oh, and would it kill you to soak your card sleeves in more goat urine?

add other stuff.

step one: inspiration. you can't build a deck with no idea how it's going to work. (well, you can, but that's not the point.

step two: figure out about 54 cards to go in the deck, searchers (not bloody tutors damnit!), pumps, characters, etc....

step three: the remaining six or about should be fillers until you test it. fillers being things you can take out if necessary.

step four: test the deck against most of the tier one decks. find out what cards it specifically loses to.

step five: replace fillers with tech to pwn the cards the deck is weak against.

step six: cheese it.

step seven: profit.

Knowing what livestock excretions can smell like, I am willing to venture that yes, in fact, that goat urine soak could end up killing me via 'teh stench'. Thanks for putting in those calls, though. I'm still pissed I didn't end up as Ares' Chosen. Oh well... hope nobody here's going to be in Fresno on what I'm calling Red Saturday.
