One of the more powerful Straining Moves thus far, SHBM is great to just end the hopes of someone running a strong ally or Dragonball deck, or pretty much anything non-combat intensive. The sad thing about this card is, it has more cons than pros. It removes your non-combats and allies too, so kiss your Trunks Effortless drill good-bye unless you're playing Orange Focusing Drill. Plus, your opponent draws 3 cards before damage is assessed, meaning that if Effortless Drill isn't out, it probably won't be successful. Also, it removes a battlegroud in play, so you can kill your own Cell's Arena or Dying Planet. Great for those who know how to use it -- novices beware. 

First time I saw this card, I thought it stunk, then I thought it was really good... now I think it can kick butt IF you know how to play it right. It gets rid of ALL battlegrounds, allies, non-combats, etc. that ANYONE has in play... including yourself. There's the downside. However, the upside is that (for me anyways n_n) I never seem to able to have a steady flow of drills and such, so I can play this card with no worries. I'm still trying to figure out other strategies... >_<

I don't see the card being in any decks other than in straining move decks, mainly because of the opponent drawing 3 cards, which unlike the removal part of the text, happens to be a secondary effect, and can hurt more than help. however, in straining decks, this card could make or break a game.. its quite good for that.

Discarding a card from your hand, bad. Removing all Non-combat, Battleground, Allies from the game, possibly very good. If successful...bad. Your opponent drawing 3 cards...quite possibly your death, especially since it is a secondary effect. You're basing your attack on an if successful connotation, and you are giving your opponent a 4 point card advantage(You discard one, they draw three). Albeit that if it is successful, it could save you the game, chances are low that it'll get through unless there's an Effortless Drill out (and at that, you'd remove your Effortless from the game too). In dire situations this card could be useful, but overall it's not one that will see an enormous amount of gameplay in any typical deck. Even in Straining decks, you still need to wait to get the perfect hand to make it effective. In Tuff Enuff, maybe a little higher rating but not much because of the possibly of an overkill if set up correctly.
