For the low cost of two mana, this 1/1 Orc Pirate provides an anthem effect whenever it attacks, buffing each Pirate you control by +1/+1 for each time you've cast Vargus from the Command Zone in the game
There are four to choose from, so which is best for you and your playstyle

Adds: Cuts: Further Upgrades If you want to stick to LOTR-only cards then I'd recommend these cards (make sure they feature the LOTR art, links on this website default to cheapest version): Ancient Tomb, Reflecting Pool, Mines of Moria, Minas Tirith, Rivendell Lands: Spiteful Banditry Removal: Sword of the Animist Ramp: Lightning Greaves, Mithril Coat, Flowering of the White Tree Protection: If you want just any adds then I suggest the LOTR card along with: Cavern of Souls all the fetchlands / shocks / abu duals, Raugrin Triome, City of Brass / Mana Confluence, bondlands like Rejuvenating Springs Lands: Smothering Tithe, Deep Gnome Terramancer, Curse of Opulence Ramp: Boros Charm, Bolt Bend Protection: , Flawless Maneuver, Guardian of Faith, Teferi's Protection, Clever Concealment, Deflecting Swat, Fierce Guardianship Adeline, Resplendent Cathar, Aurelia, the Warleader, Scourge of the Throne, Waves of Aggression Beatdown: Loran of the Third Path Removal: All Done

Mirror Room, and Roaming Throne are not rogue-specific, but the unlock the Fractured Realm side and your triggers for dealing damage to an opponent get doubled
These decks are chock full of weird jank, but of all the cards included, Kamahls Summons was one I forgot existed and would never know where to play elsewhere
So whats different this time around
