Dead Man's Plate should be renamed to Dreadnoughts.
And it's UNIQUE Passive - Dreadnought should be replaced with Momentum. You kinda build momentum before finally landing your first auto-attack that dunks hard.

Dreadnought's is just easier to say and type. Dead Man's Plate takes a little longer to say and type. Unless we like DMP abbreviations.
Edit: What I am trying to say is that Dreadnoughts sounds more like what the item should be due to how it works than just a "Dead Man's" Plate. Does it sound like it fits the theme better?
