This card isn't as risky as it might appear; keep in mind that this card does not prevent you from Setting monsters in Defense Mode.
This card would work best in any stall deck. Either result of the coin toss wouldn't affect you since you wouldn't Normal Summon or Flip Summon very often anyway; the majority of your monsters would be Set.
You can also use this card in a Zombie Deck with "Call of the Mummy". If you get tails you can still special summon a monster with Call of the Mummy or any other card that Special Summons a Zombie, like "Book of Life". This way the drawback is not so hard.
