Some characters have double resources in their kit. Some have triple resources.
I appreciate Scarlet Witch as having the first and currently only INFINITE RESOURCE.
I genuinely think this might be the single most powerful event in the game based on pure value. If there's a better one, I'd challenge you to find it.
The only downside is that you only have one and there aren't a lot of ways to recur it. Although Cameo'd Wiccan has become a fan favorite. And if you're playing Wanda in Justice, I would consider Generation X an auto-include.
Even with it being a one-of, you can usually get to play it several times without recursion because Wanda just moves through her deck that fast.
