R/W Mid-Range Vehicles (Standard)

Sideboard Tips:
Against Aggressive Decks- Bomat courier is good against aggro as it allows you to throw down your entire hand and still have card advantage. Fragmentize is also good to sideboard in because everyone will be using Smuggler's Copters. Good replacements are the 3 Planeswalkers (Although Gideon isn't that bad to keep in), the Bygone Bishops (they really only shine against mid-range or control decks anyway).

Against Mid-Range- mostly not a problem and can these decks can be played with removal that's in the mainboard, but if they seem to always have board control put in that extra Fumigate. It really depends on what type of deck they're playing to replace a card with. If they are playing threats that are out of reach by Harnessed Lighting put in Stasis Snare or Welding Sparks for Harnessed Lightning.

Against Control- Combustible Gearhulk can be good for finishing off an opponent during the late game phase, but if they don't choose to take damage you have card advantage and a 6/6 first strike in the late game. Replace any creature removal for this.

If they play 3-4 Smuggler's Copters or other threatening artifacts add the extra fragmentize

Bygone Bishop really shines against control and mid-range to keep card advantage later in the game.

The Avacyn-Selfless spirit combo is really good against aggro as it gives you complete board control and a 6/5 flyer, basically a win there

It can be hard to get Delirium with Descend upon the Sinful, but Nahiri and the Smuggler's Copters makes it easier.
