This deck is led by face commander, Tidus, Yunas Guardian: a three-mana 3/3 that allows you move counters across your creatures, and to draw a card and proliferate (add additional counters) when your counter-enhanced creature deals combat damage to a player
Second, you get to turn one artifact into another, and between Simulacrum Synthesizer and Weapons Manufacturing, we have some incentive to play multiples of these
Honestly, it probably wouldn't make the cut for any Otter decks, since I'd rather just do this with an instant or sorcery to trigger Prowess on other things
Fair warning: A fully charged Farewell can drag on a game for quite some time
Realizing this, Nyx-Fleece Ram was a card that I noticed during spoilers for Journey into Nyx , and I wanted to use it in a way to combat Burn and creature/aggro-heavy decks
