pretty sure OP was asking if spell can kill it the next turn after its played none of the spells you mentioned could be played with the +5 mana cost... on turn 5-6... as for spells that would work you could execute turn 6 if you have a minion, or weapon in play

None of those could kill it on turn 6

wonder if it stacks, loatheb-shadowstep-loatheb +10 mana cost per spell?

could backfire if the have 6+ cost spells like pyro or MC...but what are the chances of that >.>

Flamestrike? Force of Nature? In certain low mana situations, Swipe, Multi-Shot, Fireball/Polymorph, Consecration and Hammer of Wrath, Shadow Word: Death, Hex, and Kill Command. So pretty useful in my opinion.

doubtful if it stacks to double spell cost but that is a good recycle for rogues

Blue post on main page says it does stack, not sure when it would be worth it though

Kills Miracle and I'm happy about that.

Doesn't kill Miracle but it does hamper it. That 1 turn that you need to wipe out rogue is where it will really hurt them.

RIP Miracle Rogue.

No Mr Mage, No Flamestrike this time. 

and no more pyroblast :D

OMG!! love this one. 

Obviously great against Miracle Rogue and might also great against Freeze Mage. 

Loatheb's effect might as well say; "Battlecry: Opponent cannot play any spells next turn"

no because you can cast eviseriate or frostbolt or fireball tracking flare etc.

True. But you prepare to pay 7 mana for 2-4 damage? 

Lol yes that's one step in the right direction. Now to do something about warlock rush...
