Essential? Nope. Very cool? YES.
You'll be surprised how much they change the way a character plays, and in this game the more variety the better. I feel like the Freedom Six cards are especially good in terms of how much they change the character. It helps that Team Leader Tachyon is OP as hell. ;D
If you're looking for pure strength Tachyon's promo and Bunker's promo are straight upgrades IMO.
