one fun strat with this deck is when they bust out with annoying creatures, i like to mutate/return(or eat) to their hands, that way they have a bunch of creatures they cannot use, taking up spaces in their hand
but i am sure many have thought/done the same. Oddly enough though the prot art really isn't that needed if you play the cards right (Bonewall is main target of destroying artifacts) the three firestorms come in handy vs graviton and FQ.
Edit: ( I am not using shard, instead of it i use twin universe, works great on Graviton (make a copy of one of his or yours so he kills it with firelance and keeps others safe)
not that i do not have a shard, i have 6 div 4 grat, 9 un-upgraded grat and 3 un-upgraded div.
