Classics Megatron Upgrade time!?

So now Megatron is going to need his trusty energon flail to go up against Prime with his axe. I’ve had some designs ready to go. While doing research, I saw some cool designs I could go with. Like having two or three spiked spheres. However, the cost will double/triple to even get myself one made.   So I’m going to keep it at one sphere. I’m thinking of giving each spike a different height. The top spike would be the longest, then the ones around the hemisphere would be a bit shorter, along with shorter ones in between.
