Cori Steel cutter, Stormchaser's Talent, and Slickshot show off need to be banned from standard
That deck is already 30% of the format meaning you screwed up. This means you need to ban these cards to fix your mistake WotC.

This is what I refer to as the "Slickshot Otters" deck--sometimes including Leyline of Resonance for extra "spice" in BO3.
Per my earlier post today, I now insta-concede to this deck after game one. It _can_ be routinely beaten with some aggressive lockdowns (Fresh Start, Witness Protection) and flicker effects (Unsummon, Unauthorized Exit), BUT that mandates aggressive side-boarding for This One Deck, AND it's still just a route un-fun match that's "over" by turn 3.
Leyline of Resonance should've be banned months ago. Period. Not just in BO1 matches. Honestly, it's a testament to WotC's attitude that just banning a card in BO1s is seen as OK.
This just isn't my idea of fun Magic and how I want to spend my time playing it. So I simply won't be playing against this deck moving forward.
