Piston Sledge

there is a great combo with piston sledge have a stoneforge mystic out with the mana available to use its second ability (one white, one colorless, tap.. put an equipment card from your hand into play) now.. heres what i do... i make sure i have a few creatures out in play.. i suggest a mirrian crusader, and anything else you like, (flyers, and anything with pro colors..) (the double strike ablilty is key to this) and when i attack with the crusader and my other creatures, and my opponent decides to take the damage, i use the mystics second ability to "auto equip" the sledge to the crusader (or to the creature he/she doesnt block) and add an extra damage! (because of the double strike) and you can also add the brass squires too. so you can "auto equip" anytime... if they decide to stop the crusader, just use the squires ability (tap, attach an equipment card to a creature you control) ive used this trick with argentum armor too.. the mystics ability to put it into play, the brass squire to attach to the attacking creature that WASNT BLOCKED.. the sledge is great in an infect deck too... add a few more poison...
i give it a 3 star rating because if you dont use this "auto equip" ability, you have to sac an artifact to equip it..
its not a bad card.. but you need a few other cards to really make it shine....
