It sounds like you’re referencing the green node (we seem to call it the Challenge Node on the forums – name was made before they made the node green). Do what I do, if you’d like…
I play on SCL 10, as well. So this is doable… but it takes a while, depending on the team you’re against.
I have a MUCH underleveled 5* Hawkeye. He sits at 3/2/2. only THREE in that coveted purple power. The one that actually makes him worth using with Hammercap.
Hammercap and 4* Gamora are both champed.
I also put the Wong support on Hawkeye. When he matches a blue (and he will, thanks to Hammercap), you have an extra chance of making more blue.
I put the Milano on Gamora. Chance of making extra strikes on purples when she fires a power. Her stun only costs 6 blue. It’ll happen often.
And I put Sharon Carter on Hammer. Extra Blue/Red AP (and yellow, but we dont care about that) when his CDs expire.
Run those 3 together. Try to match tiles that DON’T put Hammer in front… you want him to jump in front, because he takes less damage when he does that. But it’ll still be enough to trigger his passive, he’ll throw out countdowns. If you’re lucky, he’ll get hit by a cascade of 2 match 3s. I say this because 8 CDs will set you up with Blue AP for nice long while through this match.
From this point, you’re just mainly stunning anyone that’ll cause you harm. Fire off Hawkeyes Red arrows, so that more CDs can expire eventually, giving you more blue, letting you stun for longer.
You’re targetting BLACK ap though… and maybe purple, just to clear them out. You are aiming to trigger Gamora’s insta-kill. You’re stunning the enemy team to keep the board still while you manage making every purple yours (or matched away). Black AP is your friend. For the record, I don’t fire her black power off until I know there’s only 6 or less empty purple tiles out on the board. I dont’ wanna waste the black AP if it’s not gonna give me the chance at a instakill.
Finally, when you have them all, just very cautiously match a single match 3 near the top, that won’t cascade. With enough luck, no extra purple will fall down. And the dude in front will get slaughtered by Gamora.
Rinse and repeat for the others. It’ll be easier because there’s less people to stun now.
YES THIS IS HARD. No I’m not arguing with you.
I’m just trying to give you my default strategy that doesn’t have a champed 5*. This is my “well, nothing else I have is gonna work” team.
Sure, I have 9 champed 5*s now. But they don’t work like this team. Not one bit.
I hope this helps you. I hope you have the champed Hammercap and Gamora to get it done.
Or maybe there’s another team you can use more effectively. I know a lot of people bank on Coulson instead of Hammercap. I just don’t have a champed Hawkeye to tank for me like others, so Hammer is my tank and AP generator simultaneously.
