This deck features Zixor, Apex Predator as the OTK win condition. 

In order to unleash this beast on our opponent we need to kill it off, then draw Zixor Prime and buff it once for +3/+3, and discount either it or Tundra Rhino once with Scarlet Webweaver. When we are done with all the preparations, we can combine them both on the same turn representing exactly 30 damage to the dome (2 from Tundra Rhino and (4+3)*4=28 from Zixor Prime). Needless to say we can deal even more damage if we manage to buff Zixor Prime in hand more than once which is possible if we are lucky with Scrap Shot. But we have to give Zixor Prime at least one buff and to guarantee it we use Scavenger's Ingenuity. In turn, to guarantee it lands exactly on Zixor Prime we run only three beasts which are all parts of the combo, and if possible we should create a situation when we shuffle Zixor Prime in the deck and draw it right away with Scavenger's Ingenuity. It's unfortunate that Master's Call leaves Standard exactly now that's why we can't afford any extra beasts in the build. 

The deck shell itself tries to control early and mid game through anti-tempo tools until we assemble the combo, which, considering the amount of draw should be consistently quick.
