The end-step trigger reads like a go-wide combat payoff, and it is, but the condition it keys off gives the card its real shape: any permanent you controlled leaving the battlefield, not just a creature dying. Fetching a land, cracking a Treasure, feeding a sacrifice outlet, even bouncing your own token all arm the reward. That reframes an otherwise plain attacker into an engine that wants churn: play a deck that constantly cashes in permanents, and every combat step closes with a board-wide counter and a full untap, so your creatures swing and then stand back up to block. The untap clause is what elevates those counters past cosmetics; a board that attacks and then resets to defend is a different threat entirely from one forced to choose between offense and safety each turn. Pairing with a second commander gives the shell its other axis, letting a chosen identity fill whatever the sacrifice-and-attack build lacks (card advantage, colored fixing, a second payoff) instead of locking that space into a color pair from the start. The Angel and Elephant typing share almost nothing tribally, which frees the build to chase the mechanic rather than the type line: this wants a permanent-churning attack deck, and the counters, the untap, and the flexible partner all pull in the same direction.
