should there be a card upgrade system?

so I have about 50 commons and I was thinking that if you had 50 of one type of card you could get one of the next rarity

why? I have at least ten of the rarest things except the newest stuff, nothing is so ridiculously rare and 50 times as good as the item below it. This just seems unnecessary

yah but you would only get one next rank item for the 50 cards

I really like that idea.

thanks

thats could be work

ok, I was vague but if you had 50 common boost or weapon reqs you could exchange them for 1 uncommon boost or weapon. it depends on of the type of item you but in so boosts for boosts and weapons for weapons.

so basically you would get one tier above the one that you got.

This would be a great addition because people would now have a reason to keep req cards for the chance to get better items
