This card is amazeballs. It provides a permanent bonus (making Colossus a 2 THW) and provides him with unprecedented card draw. Colossus' gameplay conceit is that he uses tough status cards as currency, which makes this upgrade a card draw funnel. The best part about Colossus is that he gains a Tough whenever he changes to Hero form, so there is always grist for whichever mill you choose to exploit.
