thanks for the feedback.
You are forgetting it can still attack. So you got your -1/1 AO, bless it and it deals 2 Damage per turn, that s not impressive i know. But there are a lot of buff cards out there so it won´t stay 2/4 for long.As bigger as it gets the more your opponent is forced to handle the creature and when it finally dies you are left with a much bigger problem , the poison. There is currently just 1 way to get rid of it and that is Purify, and most decks don´t run it. And something like 10+ poison out of nowhere is nothing to laugh at.
This way your one trick pony deck (like Pegasus+Blessing) even gets something out of your "wasted" buff cards after the creature dies. Turning Pegasus/Blessing major flaw (you spend like 3-4 cards to buff your creature and after it dies you run out of steam to finish your opponent).
The main reason that its attack has to be below 1 is Fractal. Extreme low cost + a creature that does something on dying would be overpowered.the -1 definatly prevents any Fractal abuse - you would have to go for Twin Universe to get more out of it. Another reason the attack has to be low to prevent going "overboard" with the current copy cards and ones that might follow later.
