Wall of Lost Thoughts enters as a 0/4 defender that mills four cards — immediate, guaranteed value at two mana before it ever taps for anything else. In Phenax, God of Deception decks, that four toughness becomes a mill engine on its own, making this one of the cleanest two-drops the archetype can run.
Best Commanders
Commanders with the highest synergy
Phenax, God of Deception
Wall of Lost Thoughts is a natural fit for Phenax, God of Deception because toughness directly converts to mill — a 0/4 that already milled four on entry and then taps to mill four more every turn is exactly the kind of recursive threat Phenax wants.
Bruvac the Grandiloquent
Bruvac the Grandiloquent doubles every mill trigger, so the four cards Wall of Lost Thoughts mills on entry become eight, and each subsequent tap activation doubles as well — cheap, repeatable, and immediately impactful the turn it lands.

Wall of Lost Thoughts is a Commander card — full stop. The mill-on-enter trigger and high-toughness body are designed for the 100-card singleton format where milling four matters and a blocker with four toughness survives long enough to keep tapping. In Modern and Pioneer it's legal but irrelevant; dedicated mill decks in those formats have faster, more scalable options and no use for a 0/4 that doesn't attack. Legacy and Vintage don't want it either — the power level is nowhere close. Stick to Commander, specifically the mill archetypes where Wall of Lost Thoughts earns its slot.
