What it does
Aberrant Tinkering isn't a standard rules keyword—it's an ability word (or flavor text label) used to tie together a specific card's effect. Because it carries no inherent rules meaning, you must read the card's actual text to know what it does; the words "Aberrant Tinkering" themselves do nothing mechanically. Ability words like this just group thematically similar abilities for flavor.
The most common mistake is assuming an ability word grants reminder-text functionality or interacts with cards that reference keywords. It doesn't—it's purely cosmetic, like Landfall or Constellation. Effects that say "for each keyword ability" or that care about named keywords won't count it.
In Commander, this matters mainly when evaluating templating: don't expect synergy from the label itself. Trust the printed effect, and if you're unsure, check the Oracle text on Gatherer or your rules reference, since flavor labels can mislead deckbuilders.
