The list of ability words, updated through the Eventide set, is as follows: channel, chroma, grandeur, hellbent, kinship, radiance, sweep, and threshold
Super rare and secret rare cards are very important if you are interested in playing the TCG, as they are often the highest rarity cards needed to optimise certain decks
Meanwhile, Brudiclad, Telchor Engineer has made a name for themselves as a bizarre yet enjoyable tokens and artifacts commander

The -2 is also pretty useful, especially in Commander where its difficult to generate true card advantage over three opponents
