The goal in most casual circles isn't really to win the most games
Word of Seizing is a bit long in the tooth now, but it can steal any permanent, which makes it surprisingly versatile
If the triggered ability can't determine the information it needs, or if it can't find the objects it expects to find in certain zones, those parts of the effect just do nothing
it also works well in the 99 of commanders like Maarika, Brutal Gladiator, which uses menace to kill more creatures, and Kelsien, the Plague to give it deathtouch for the ping ability
Barbed Servitor Im sure the Brash Taunter EDH combo decks are interested in Barbed Servitor, and that dude on MTG Arena who plays deathtouch creatures and fight spells while struggling to make Diamond is totally gonna play it
