When The Mouth of Sauron enters, target player mills three cards. Then amass Orcs X, where X is the number of instant and sorcery cards in that player's graveyard. (Put X +1/+1 counters on an Army you control. It's also an Orc. If you don't control an Army, create a 0/0 black Orc Army creature token first.)
Mill yourself (or an opponent) to fill a graveyard with instants and sorceries, then build a huge Orc Army token off The Mouth of Sauron's amass trigger. You grind value with spell recursion, flashback, and self-mill while assembling one big threat to swing for lethal, ideally with evasion or a doubler.
Repeatable amass off blink/recursion makes a fast, large Army token
Self-mill fuels graveyard payoffs, flashback, and reanimation
Blue-black gives premier card draw, removal, and counterspells
Single-creature payoff is easy to protect and pump
The Army is a single creature vulnerable to spot removal and board wipes
Filling the graveyard helps opponents' graveyard hate hurt you more
Voltron-style plan stalls if the Army gets chump-blocked without evasion
Five-mana commander with no immediate board impact beyond the token
Pairs with spell-heavy self-mill themes and provides backup threats if the Army dies.
Add counter doublers like Doubling Season and Hardened Scales plus reliable blink (Conjurer's Closet, Ghostly Flicker) to spike multiple amass triggers. Layer in evasion and protection (Whispersilk Cloak, swiftfoot/lightning greaves) so your single Army isn't blanked by removal, and lean into a tight instant/sorcery package with flashback and Snapcaster-style recursion to keep the trigger huge each cast.
