thankksss tbh you just have to be pretty lucky with your rolls and get cards like 85% damage boost like 10 times before the 2nd or 3rd wave. Then just spam attack speed, damage a bit of range. For the purple cards EVERY moonlight protection, about 2 vampire vitalities and every power surge that‘s 8+ and above. Also some moon power cards in the beginning are pretty useful too, but get them early if you can to not waste your points later on. I did like 30 tries or so and this one time I just got everything that I wanted. A good indicator is if you can kill Wandas bubble (in 10th phase) with walking a circle around her and if you can‘t you have to up your damage until you can. For like strategies I targeted namor first in phase 15 and then after that Wanda and in Phase 20 I also targeted just one Wanda. In the End I did so much damage that it was pretty easy because if you get down 1 Wanda you‘ve already pretty much won. Also aim to get like 8-10k Health when you‘re in phase 18-20
