Just started, thinking about some poorly rated sets...

I had Ghostrider+Hobgoblin. Got No Way Home final battle combo, Milano and New Ship to have all the guardians, and Ultron battle for the main avengers. Next 2 big buys look to be endgame battle and Xmansion to fill out the character roster I want: the core X-men team, Magneto, thanos, antman, SW. I'd also like to get Carnage and Venom somewhere. Any suggestions for the big purchases and Carnage+Venom? I'd love to get the "girl power" endgame set since I have 2 daughters but looks like I'm...
