I'd recommend deploying small low-tech mobile teleportation blockers against Marciano, then. I can (vaguely) remember a battle where one of my chars was fighting one of TE's chars that teleported everywhere in combat. I think the char was named The Chezchire Cat or something along those lines? Anyway, the first thing my char did was throw down an anti-teleportation rune or something like that so that the fight would be fairer and it worked because they both defeated each other and both nearly died (I think).

Those were good times! In fact, I'd go so far as saying that they were fantastic super awesome times!
