it's a good deck, anyway, you don't have anycard aganist creatures, what if you meet a squid or a parasite?or an oty? or ma maxwell demon? there're a lot of cards thath can give you a lot of truble
add 1/2 drain life, add some devourer, trow away some pillar(i prefer to trow away a dragon too for 5 total dragons, thath it's still a good number)
