Who do you think the best heroes in the game are? Who are good in nearly every situation AND when ideal conditions exist act like a cheat code to the win? Here's my list in no particular order.
1. Prime Warden's Argent Adept - He needs almost no time to set up thanks to the extra card play and can almost always activate something useful. If opponents aren't constantly destroying cards, he grants the biggest bonus of everyone in the game. That extra hit point is pretty great, too.
2. Prime Warden's Fanatic - this is the iffiest member of the elite for me, as playing that accidental End of Days can be a huge problem, but with a bit of ongoing destruction going after her, it shouldn't be the end of the world. The extra power use and card play is huge, as are the benefits she gains from lower HP and digging through her deck.
3. America's Greatest Legacy - Extra power uses are huge, and Legacy has a ton of utility in his deck. That heal comes in very handy as well.
4. America's Finest Legacy - the easiest damage boost in the game with all the great combos one could wish for. He has a simple 2-card combo that nueters multiple villains, too.
5. Nightmist - Nightmist is a monster with her amulet. If she doesn't see it (through massive draw or search) quickly, then you can always stick her in Mistborn for awhile to dig even faster and keep her safe. She can also shut down the villain deck and heal to full.
6. Parse - Parse kills ongoings and enviornments like no one else,but she also does damage, creates multiplies and manipulates the villain deck. It's completely possible to play her in almost any way the game calls for to great success. She doesn't always feel that great or fast, but I've found that a game with her is always far easier and far less likely to be a loss.
7. The Scholar - With his ultimate set up, which can only take a few turns to set up, he's nearly impossible to kill and lets off huge damage. What sets him apart from others this is true of, like A/Z, is that he can also be useful while setting up, tanking huge damage, or after a reset,
8. Team Leader Tachyon - Everyone loves draw, and everyone loves huge bursts of damage. This Tachyon draws so much she can handle nearly any situation and unleash massive boss ending attacks, sometimes in the same turn.
9. Visionary- She can make multiple bosses and games a joke if she sees an early Wrest the Mind, Brain Burn, or Twist the Ether. She can search for these with her power, and control the villain deck in top notch manner. She makes ongoings a joke, or gives you back your very best. She even has more survivability than one would think thanks to the Decoy Projections and her Coccoon. She's always got something great to do.
10. Wraith - the fastest set up and best survivability, Wraith does everything from controlling the villain deck to stomping ongoings and enviornments to massive damage to damage reduction and prevention to fast draw and card search. She doesn't actively help the team besides herself (but then there's smoke bombs) but everything she does is a huge boon.
Honorable Mention: The Sentinels are phenomenal, but they do nothing to Ongoings and a villain who targets the lowers consistently enough can leave them little to do but heal. Omnitron X is a beast who sets up wildly quickly, but big damagers and ill timed equipment destruction can leave him searching for a way to help. Setback can be a beast, or see useless cards in the wrong order. A/Z set up without destruction can win games, but he has to see that set up and any destruction can ruin him. Of the bigger hitters, only Haka really warranted consideration, as he's the most self-sufficient since he can heal and draw on his own. The newer Naturalist will almost certainly make my elite tier fit 11 characters, but the current version suffers too much if you have the wrong card for the wrong time.
