Would this affect the bazaar? I mean, would I have 3 or 6 of these in my deck, individually, because they are, in most cases, treated as one creature.
Another note: For the passive competition, you might have a spell card that gives the passive ability 'Twin'.
Twin: Link two creatures on your field. Both are affected equally.
They would be buffed, damaged, and die together, no matter what their stats. Essenially, you would be able to buff twice your creatures for the same cost at the risk of being twice as vulnerable to CC.
If you don't want it, I'll take it.
