:HOW TO BREAK THE DECK:
the idea is to un-ban 1 card from the forbidden list putting it to 1 for a specific deck... in order to boost the deck to the next level .... and would do the most damage if it came back.... give some who what and whys to back up your idea ....just try to stay away from super generic cards to make this more interesting
my choice would be Exchange of the Spirit for Lightsworn decks
since you will probably have the 15 cards needed by turn 2-3 it will be live pretty regularly.... getting it might be an issue but would be damn cool IMO
so what banned card would you give to a deck?
