Infinite Loops in Dice Masters

Say, for instance, that I have Ork Nob: Big Choppa and Doctor Doom: Reed Richards' Rival in the field, and I field Ork Boy: Shoota on level 1.
This appears to trigger an infinite loop, as Ork Boy is not an optional ability. He would repeatedly receive the -1D from Doctor Doom, be KO'd, then returned to the Field Zone at level 1. This would result in Ork Nob gaining an infinite amount of Attack and Defense.
Does the game end in a tie? What happens in single elimination after a top cut of a tournament?
This "combo" can also manifest with an opposing Valindra Shadowmantle: The Right Hand of Szass Tam.
When a character die is KO'd, Ork Nob gets +1A and +2D (until end of turn).
While Doctor Doom is active, each non-Villain character gets -1A and -1D (no matter how many Doctor Doom dice you have fielded).
When Ork Boy is KO'd, if you control a (Orks) character die other than Ork Boy, return Ork Boy to the Field Zone at level 1 (clear all damage from Ork Boy).

While Valindra Shadowmantle is active, opposing non-evil character dice get -1A and -1D.
