Definitely agree that Thor and Black Widow are a solid base. I've never been big on Human Torch, but Vyx has some good points. Personally, I'm entering the later stages of the three-star transition, so I use 3* Cap & Black Panther with 2* Storm. Storm gives great AP mining ability with her green, and one of the best AOE attacks in the game with her blue. So as an alternate team, I would suggest, if you're limited to strictly 2* characters, Thor/Storm/Magneto. There are downsides, of course, as this leaves you without a backup plan for any countdowns you can't match, but it's a typically effective team.

And you can start looking to pair Thor and Black Widow with a three-star character as soon as you start getting them to about the 114-127 range (8-9 covers). I'd have to see your roster to be able to give you any more specific feedback.

As for actually trying to find you a solution to your question... if it were me, I'd go with Wolverine, Bullseye, or Cap to round out the two-star team.

The beautiful thing about Thor/BW pairing is that, between them, you guarantee decent damage on any match (Thor takes red, yellow, and green; BW takes Purple, Blue, and Black). The only hole of any sort is that BW's black power is passive, so any AP you accrue isn't really usable.

Of the three I suggest, only Bullseye would allow for that black to be put to use, and it drops random critical tiles onto the board, which could be useful on Waves 2 & 4. Meanwhile, his purple is passive, and helps to minimize the damage you take. His green, which would compete with Thor's, so you wouldn't use it often, could be used situationally if you can find a way to manipulate the fall of tiles to generate crits, otherwise, it's just a shot in the dark for a cascade and some moderate damage.

Wolverine would likely be my first pick. His yellow passive allows him to heal while also generating AP for Thor's best AP-generating move. His green would compete with Thor's, but might actually be worth getting off at least once, and here's why: Black Widow, with her black maxed, can do ABSURD damage when she has bonuses to attack. We're talking a total of 1-2k damage on one match, potentially. Lastly, Wolverine's red doesn't generate yellow tiles, but it does three times the damage of Thor's red.

Then, there's Cap. He pales in comparison to the 3* Steve Rogers, but he can be useful. Set him for 3/5/5. His yellow drops some decently-powerful protection (with this build, three at 148 each) in case of emergency (if Thor bites the dust). His blue and red will not only, when maxed out, override enemy countdowns, but return a decent portion of the AP if you can protect those tiles, meaning it's a continual output instead of having to start from scratch.
