Boostier 1 & Boostier 2 (available in each booster slot) - Enables use of two boosters in the other slot. ... so in other words, you can use two from any slot, instead of one from each... would have to be a very high, if not the highest booster in each slot... But I truly believe this is one people would REALLY like (if not downright excising the slots and pooling them all together).
Seeing Red (BOH) - No damage indication, black and white, or red.
Least Likely to Succeed (BOH) - A first, a low-leveled badge of honor, maybe even JUST for levels 1-15, I think they should have a couple for those who want a challenge off the bat... and in this case, it would give an extra 10,000 if you lead your team at the end of the match (and whatever the mode)
