I don't like having this thing be too easy to kill, given that the things it makes already are.
More importantly, making it a 4|2 is a big nerf. Its underpowered already, so we wouldn't want to make it weaker.
Currently it is a 3|7, and 1ATK is worth about 2 HPs, so that would leave a 4|5 ... to keep HP lower than HPs, you would want to bump it to a 6|4 probably... not sure if that is too tough for a cost of 5 though.
