Any tips that I can get? How can I improve?

What characters do you use ???? 

" What characters do you use ????  "

Well i personally use  
 
Thanos 
Juggernaut 
and venom
 
 
Thanos i use because he has really good ultra moves and i love his capture bubble , Juggernaut is a beast and venom is tricky to hit if you play him right .

I'm thinking that I'll end up playing a mixture of faster characters. Who are the better/easier to play faster characters?

I'm also new to the game and would like some tips to get better, I am really horrible, I can't even beat the game on easy lol. 
 
I use, Jill, Akuma and Venom.

Just use Magneto, Sentinel and Storm you'll win every time, also i'll despise you!  
 
Jin, Ken and B.B. HOOD ftw!!!

my ultimate noob team is akuma, cable, and wolverine.
 
akuma is really easy to dominate with if you've ever played Street Fighter with a shoto character.
cable is considered a god character with some infinite combo's but basically his pistol and viper beam is a noobs best friend.
wolverine is what i place all my button mashing friends on, super easy to learn and is really fast
 
 
you can also swap out cable for cyclopse who is alot faster and is the closest out of the marvel character to being a shoto street fighter

 Hey I'm absolutely new too, didn't want to start another thread though. I mean I have some arcade experience, and I know some basic stuff, but I only played very sporadically over the past 8 years, so that barely counts. I notice I tend to use (and succeed more with) a team of CapCom, Strider and Iron Man. But I heard of this famous Doom and Strider pairing, and I'm thinking of subbing out CapCom for Doom. I seem to play fairly well with Doom anyway.  
 
 
Would any of those teams be seen as "cheap"? (I know there's a lot of arguments going on about what actually constitutes as cheap, or if there even IS cheap, but still drop some opinions)  
 
Also I'd love any kind of solid beginner tips, keeping in mind I'm a very offensive type player, and I like fast, hard-hitting attacks. Oh and beams. Beams are fuuuuuun! 
 
Thaaanks!
