I present one solid counter argument: what makes you care about that
2023-06-16 Amass abilities are now written as "amass [subtype] N." Previous cards with amass have received errata to say "amass Zombies N." 2023-06-16 To amass Orcs N, if you don't control an Army creature, create a 0/0 black Orc Army creature token
This doesn't inherently mean anything, but another ability on the card will somehow refer to the Mount being saddled
Sheoldred March of the Machine provided us with a very good sacrifice effect that can be later transformed into a saga that further punishes unprepared opponents
so - The above deck list and explanation actually comes from a post in my brand new community where members have access to my decklists, metagame predictions, and discussions with me (I also encourage members to bother me for a deck list if I havent covered an archetype youre interested in!)
This allows you to put your choice of a +1/+1 counter or two charge counters on up to one other target artifact, at the beginning of combat on your turn
