if it was 1 spell would be playable 1/5

Great card, most poeple comparing it with mana tide stats wise but i think you really missed some important points, this have stealth for 1 turn unlike mana tide it will most of the time avoid being insta removed during opponent turn and ALSO can draw the card ( and more than one ) DURING your turn ( and not at the end of it ) meaning u can use the spell right away and even chain the draw.

IMO its a great fit into aggro shaman ( and not only ), t5 Doomhammer t6 spirit + lighting bolt, spark or the new spell = draw rockbiter, if its still alive on turn 7 its 10 via doom+ rockbitter then u draw a lava burst…

good stuff i would change 3 cards

-1 zap -1 fire plume phoenix -1glacial shard
+ Kalimos + 2x Elementary reaction == fix last game refill or burst + 7/7 body and the reaction draw 1 card+copy for 2 mana is great refill

u better SNIPE this

not sure if this is that good

the beast pay it, not you

and maybe commanding shoot

i added 2 stonehill for extra statue / rotten applebaum value, i dunno about DK cause we have lot of 5+ minion we could self kill with his battlecry

i made that deck, pretty much getting value from bone dragon and tomb lurker since all deathrattle are 5 mana +, need some work you free to comment/suggest : http://www.hearthstonetopdecks.com/decks/quest-priest-witchwood-theory/
