Last I posted, I was on 6.2.6 with Sorcerer Supreme and had no idea what I was doing wrong and was dying so much. I watched some videos, read some guides, and tried so many times. The answer? Just spam SP1 as many times as possible. So I got to 6.3, and it seemed a lot easier than 6.2 to be honest. The paths are a bit worse because of the higher healthpools, but overall not too bad. I breezed through 6.3.1-6.3.5, and then stopped at 6.3.6 because of the CapIW boss. The best option I had was Sparky, who was at r3. I took him to r5 thinking it would make the fight a breeze. I made a big run the first day I unlocked it, thinking it would take me one or two revives at max. To be fair, I did use 2 revives, but I only took 25% off of him. So obviously I quit out and saved up some more units and made another run 2 weeks later. That run came around, and I failed again. 2 weeks later, failed again. I felt unmotivated to play the game, like I was stuck and I had hit my natural skill ceiling. Eventually, I saw this post yesterday morning around 9:00 AM EST:
Thought on the 6.3.6 Cap IW Boss This is what inspired me. I took a run, and tanked the boss down in 5 revives. I was so happy. The rewards weren't too bad, since I first time duped my Mr. F, but only 3*s from the Cav crystals. I didn't even think that I would want to attempt 6.4.1, since it took me 200 units to do 6.3.6, I couldn't do 6.4.1 with 30 units. Saw the videos and the guides and took a jab at it. The results? I'm here now.

That said, any tips for 6.4.5 Hydra Adaptoid? From what it seems, Cap IW is a good counter, and Tigra works better, but she looks harder to play. Thanks and have a great day. (Here's my roster for reference if that helps for your suggestions for 6.4.5):
