This card is one of the most powerful anarch card there is.
It combine well with Rejig and Simulchip. The later let you put it back on an ice after the corp trash their (now useless) ice. The former let you put it back on another ice that need more effort to break.
Against single sub ice, this card is even better, since a purge will do nothing to it.
Being a virus, you can make use of MemStrips to have the MU for it.
With Botulus, you can make get a lock on a central without problem. This open up so many lines of play.
The art is evocative and will make the corp shudder. The joke in the quote will get old very quickly, but can be a running gag also. This give the anarch a powerful tool to deal with super ices without having to use tools imported from other factions. In my opinion, this is a top tier card.
