You know you're famous when someone links a thread you created.
Yes I had a similar idea to this, but I attempted to fix the problem another way.
The upped would still allow for a 5 card titan 200HP OTK which is a terrible problem. The unupped is not that OP but perhaps would be underused. A massive dragon plus this would give a 15|8 creature that's poisoned, compared to a PU that would give a 2 8|30 creatures (Obviously better).
