What special cards do you think are the best:

*Heroic Feats

Or

*Benefits of Training

And why?

Tried looking at it, but can't decide.

Both got some good and awful cards.

One card in particular seems really meaningsless. That one where you, after teams have set-up, can switch one player on the pitch with one player from the reserves. Why? Keep a big nasty killer on the reserves to lure some opponent to the pitch or line of scrimmage?

I would say Heroic Feats for the extra MVP. I like them both and generally pick one of each.
