Cloudshredder Sliver

Commander is where Cloudshredder Sliver does its best work — the format's multiplayer damage math rewards wide flying boards, and the haste clause neutralizes the summoning-sickness tax that normally slows token swarms. In Legacy and Vintage, Sliver tribal is fringe at best, and a two-mana anthem with no immediate impact on a non-creature board rarely earns a slot in those formats' faster environments. Modern Slivers exists as a budget tribal option, and Cloudshredder Sliver is a legitimate four-of there — flying plus haste on a two-mana body is the kind of redundancy aggressive tribal needs. Oathbreaker follows the same logic as Commander: Sliver-centric builds want it, everything else ignores it.
