so.. if you have 1 of this + SoR + sparks + photons, you will soon be unsoppable?
when the first is in play in 2 turns you can have 4 of Beelzebub and so isn't your victory already claimed?
i like the idea but i think it's OP and unbalanced (especially -2/-5.. if you have 1-2 of this in play, how many creatures there are that can handle 5-10 damages? most of the creatures with the exception of flying titan, armagio and colossal dragon won't survive against 10 damages.. i agree with the -2/-5 for 5
, it's balanced, but it's OP and unbalanced if this will create another Beelzebub)
basically.. i think it's better to lower the cost of the ability to 4
, to rise the cost of the upgraded card to 9
('cause you already give him +1 atk) and lower the negative bonus he gave to target in the upgraded one.
that way i think it's more balanced.
