This card is an average card. There are 2 major problems though, which can either be considered offensive bonuses, or defensive bonuses (if you're on the receiving end of the attack). #1, the attack is mega weak. One life card of damage is not much. The 5 cards your opponent discards from the if successful effect aren't damage, only discards, so blue cradle drill and Frieza is Ready won't work against it (once cradle drill gets re-worded). 

But the randomness is crummy. After the 1 life card of damage, you get to see if the card you trashed is a physical attack or not, then the +5 is assessed. It is an OK card, but i'd rather use something like Blue Right Cross or Blue Energy flight that does a guaranteed 6 life cards of damage if they hit.

In constructed and Tuff Enuff, the environment isn't always overloaded with physical attack decks which makes this card's deck value go down. Not to mention the additional discards are if successful. It's got a nice twist, but overall it won't find much play.
