Lotho, Corrupt Shirriff

A 2/1 with no immediate return is easy to answer; it may be tested in WB value shells, but second-spell Treasures are unreliable in 1v1.

Could be wrong if A cheap, resilient shell that routinely double-spells could make the mana engine materially better.

Legacy's cheap spells can trigger Lotho, but a WB 2/1 that must survive is a slow engine against highly efficient interaction.

Could be wrong if A white-black shell able to exploit repeated Treasure while protecting Lotho could establish a niche.

Multiple opponents naturally casting second spells can yield several Treasures per rotation, making this a strong low-cost engine despite life loss and removal risk.

Could be wrong if Optimized tables may deliberately limit second spells or remove Lotho before it produces enough mana.

The 2/1 body is mediocre, but sequencing a second spell can bank useful fixing or mana; it is not reliable enough to be a premium pick.

Could be wrong if Unknown set speed, cheap-spell density, and removal determine whether it survives to generate meaningful Treasures.
