Lord Xander, the Collector embodies Tzeentch, the Changer of Ways — a deck built on schemes within schemes, where nothing that happens to it is truly a setback. The deck is a self-sufficient spellslinger that must function without Lord Xander on the battlefield: his 7-mana cost means he is a powerful finisher and bonus, not the engine. The core gameplan is instants and sorceries amplified by spell copying (Thousand-Year Storm, Double Vision, Reiterate, Reverberate), cost reduction and draw (Archmage of Runes), spell recursion (Kess, Exalted Flamer of Tzeentch, Snapcaster Mage, Cormela), and casting spells from places other than hand (Keeper of Secrets payoff), giving a chaotic "cast whatever you find" Tzeentch flavour. Alongside this runs a "punish whatever they do" streak: even when opponents do something they think helps them, it costs them. Opposition Agent steals their searches, Deflecting Swat redirects their removal, Massacre Wurm and Vicious Shadows turn board wipes (theirs or ours) into damage, Arcane Denial fills hands for Vicious Shadows, and Lord Xander's death trigger punishes whoever removes him. When Xander does land, his enter, attack, and death triggers strip opponents of hands, libraries, and permanents as a finishing blow. Graveyard recursion, reanimation (favouring flexible pieces like Living Death and Puppeteer Clique that use opponents' creatures), and direct damage payoffs ensure that board wipes, counterspells, and removal all feed back into a relentless engine that adapts and grinds opponents out of resources.
