My idea was altered a bit so it has reduced energy cap and a shadow ability. Other than those two things, my idea is eclipse.
Your description is not even close to how eclipse is or how it works🤦♂️ I have it; it's a beefed up shadow with 24 energy that's immune to emp when ability is activated. It doesn't remove any debuffs like redeemer does. They've been adding epic or legendary version of older, lower grade mechs for awhile now. Eclipse builds off that. The concept of eclipse was introduced before your post. I've also seen players talk about wanting a mech that's immune to emp ever since zephrys were a common occurrence last year, with redeemer being the first step, so to say this was your idea is quite a stretch...
