How it works
Activate Triskelavus by paying 1 and removing a +1/+1 counter from it, creating a 1/1 Triskelavite artifact creature token.
Activate Ashnod's Altar by sacrificing the Triskelavite, adding CC.
When the Triskelavite dies, Battle of Hoover Dam triggers, putting two +1/+1 counters on Triskelavus.
Repeat.
Once you have infinite colorless mana and +1/+1 counters, you may forego sacrificing the Triskelavites.
This ingenious loop turns Triskelavus into an endless factory by leveraging the Legion side of Battle of Hoover Dam, which rewards each creature death by placing two +1/+1 counters back onto Triskelavus to replenish its ammo. You simply pay to spin off a Triskelavite token, feed it to Ashnod's Altar for a surplus of colorless mana, and let Battle of Hoover Dam's triggered ability pump the original artifact creature so the cycle can repeat indefinitely.
