The Commander

Whenever you cast a legendary spell, untap Rona.

{T} : Draw a card, then discard a card.

{5} {B/P} : Transform Rona. Activate only as a sorcery. ( {B/P} can be paid with either {B} or 2 life.)

Trample

Whenever a source deals damage to Rona, that source's controller exiles a card from their hand at random. If it's a land card, you may put it onto the battlefield under your control. Otherwise, you may cast it without paying its mana cost.

Guide

Gameplan

Deploy Rona turn two and start looting to set up your graveyard and dig toward your engine. With a high legendary count you can untap Rona repeatedly to chain card filtering, then either transform her into a trampling beater or pivot to a graveyard/spellslinger payoff. Most builds use the looting to fuel reanimation or value strategies while building toward a focused combo or storm finish.

Strengths

Cheap, repeatable card filtering that smooths draws and stocks the graveyard from turn two
Untap trigger makes Rona effectively free to loot every time you cast a legendary spell
Color identity (Dimir) gives access to the format's best tutors, removal, and reanimation
Back side is a resilient trample threat that punishes opponents who try to fight it in combat

Weaknesses

Front side does nothing on its own to win and is fragile to spot removal
Transforming costs a hefty sorcery-speed activation, which is slow
Loot-only filtering doesn't generate raw card advantage without graveyard payoffs
Heavily reliant on a critical mass of legendary permanents/spells to exploit the untap

Key Cards

Sakashima of a Thousand Faces — A legendary clone that can copy your best legend and trigger Rona's untap while doubling value engines.
Urza's Saga — A legendary land providing repeatable looting fuel synergy and a tutor for combo pieces.
Entomb — Pairs with looting and graveyard payoffs to set up reanimation targets immediately.
Reanimate — Cashes in the cards Rona discards by returning a huge threat for one mana.
Thassa's Oracle — A compact win condition that loves the deck draw/dig and ends games with self-mill or empty library.

Upgrade Path

Lean into fast mana (Mana Crypt, Dark Ritual, Lotus Petal) and premium tutors (Demonic Tutor, Vampiric Tutor, Entomb) to assemble reanimation or combo lines faster. Add more low-cost legendary spells and clones like Phantasmal Image to abuse the untap trigger, and round out with compact wins such as Thassa's Oracle plus Demonic Consultation. Tighten the curve and add interaction (Force of Negation, Mystic Remora) so you can protect your engine in higher-power pods.

Spellslinger/Storm — Casting cheap legendary spells repeatedly untaps Rona and chains card selection toward a combo turn.
