Is the copy 'almost identical' to the target, or does it have the base stats?
Eg. player 1 plays an Otyugh and plays plate armor on it.
player 2 converts the Otyugh
Is the dark Otyugh 0/11 or 0/5 ?
If it's the first one then without other cards help it only serves as a lobo in case your opponent does not have
quanta.
If it's the second one, it serves as an anti buff/debuff card too.
Also, can it be used on darkness cards?
Does it trigger 'on creature death' events? Eg. if target was Aflatoxined? I guess it does not, but if target is destroyed you have to specify such things.
