This card would be most effective against an army of tokens. Otherwise, it can
partially control anything that produces only 1 damage at a time (Rakdos
archetypes), but your creature-base will still be vulnerable. Using this sort of
card is a gamble, as it targets a very specific type of deck, so I would only ever
use it if I thought those decks were a danger, and keep it on the sideboard.
