This ingenious setup turns a humble creature into an overwhelming multi-copy win condition by stacking your combat triggers just right. You begin by equipping Helm of the Host to Biovisionary so that combat starts with a fresh token copy, perfectly bypassing the legend rule. Simultaneously, Brudiclad, Telchor Engineer generates a Phyrexian Myr artifact creature token and uses its mass-transformation ability to turn every token you control into an exact copy of that Biovisionary token. Because you now control four or more creatures with the exact same name, the surviving Biovisionary triggers at the beginning of the end step to instantly seal your victory.
