Tresserhorn's Lord, Returned

Modern demands immediate, low-cost impact; this needs five mana and three creatures before functioning, while handing the opponent three cards.

Could be wrong if An unusually efficient token-sacrifice combo could use the repeatable draw trigger as an engine rather than a fair payoff.

Even fast mana does not bypass its three-creature ETB cost, and a five-mana setup permanent that gives three cards is inefficient for Legacy.

Could be wrong if A dedicated fast-mana token engine could make its repeatable sacrifice draw ability uniquely exploitable.

Token-focused sacrifice decks can afford the entry cost, then turn every sacrificed creature into a card; indestructibility improves its staying power.

Could be wrong if The five-mana cost, strict entry payment, and opponent's three cards may leave it too slow versus stronger sacrifice payoffs.

With three expendable creatures, it leaves a 10-power indestructible trampler and refills three cards, but three colors and the forced sacrifice are major costs.

Could be wrong if Unknown fixing, token density, and exile/bounce removal could make it either a premium build-around or too inconsistent to run.
