Most board wipes are low-toughness based, with the exception of Fumigate at rare.

Two cards: Aviary Mechanic and Paradoxical Outcome, are only self-bounce.

KLR is missing a hard counter spell at common or uncommon, but watch out for Metallic Rebuke.

There are some discard effects, but very little targeted hand disruption.

Given that many core cards are artifacts, Disenchant effects are quite main deckable.

Destructive Tampering is very maindeckable with lots of artifact targets, so beware.

Commence the Festivities is probably as bad as it looks, but careful of the lethal swing blowout potential.

Some amount of haste exists in KLR, but mostly at rare.

Lifegain is prevalent and probably better than usual in a somewhat aggressive format.

Fixing is possible in KLR, but mostly supported at green. Although, Prophetic Prism and Renegade Map are both colorless fixers that may enable third color synergies.

Some ramp exists, mostly in Green.

Dawnfeather Eagle will be a big player in race situations, keep it in mind.

With Fabricate, there are a lot of 1/1s in KLR - making ping effects more useful, and X/1s less so.

At uncommon, it is unlikely Minister of Inquiries will be much of a mill strategy.

Two Mind Control effects exist in KLR

Hijack can steal Vehicles or even utility artifacts.

Vehicles have appeared in several sets since Kaladesh was originally released. They are non-creature artifacts that can be turned into artifact creatures by tapping enough creatures with power equal to or more than the Crew cost.

Vehicle payoffs are in White-Red colors, but there are not many.

Renegade Freighter from original Kaladesh is notably missing from the vehicle list.

Energy is resource that can pay for activated and triggered abilities. Cards grant Energy counters and you can spend these counters on various effects.

Energy is the showcase mechanic of KLR, and shows up a lot! Most cards that add energy can spend it as well.

Fabricate allows creatures to enter the battlefield with either that number of +1/+1 counters, or that number of 1/1 Servo Artifact Creature Tokens.

The abundance of 1/1 Servos make this format unique.

Revolt is a mechanic which triggers if another permanent left the battlefield for any reason before you cast the card.

There are obviously many ways to enable Revolt, but cheap Sacrifice abilities are the best way to guarantee a trigger, so they are listed here.

Improvise is a mechanic that allows you to tap Artifacts to reduce the mana costs of cards.
