I love the 99 mana cap games too! This battle replay isn't mine but I think this is the most mana expensive cards you can put in a single match. Clash of the Titans between hossainbd and @glory7! So satisfying to watch.

Thanks for sharing this great replay. I'm sure @glory7 didn't find it so satisfying when he was unable to finish off the hydra.
