Just play this shit like the agro decks of old. 

you can try the clasic counter spell mirror entity package but i preffer this package for stalling the game. there's too much agro for mirror entity and not many spells to counterspell because you dont really care about board clears with this deck. its good vs murloc paladin but i usually burn them before they can tip any scales .

if you can, keep the secret off ancient mysteries to play on the same turn as cloud prince.

kobold sandtrooper- looks like a meme card but in this deck its a frostbolt on a stick, just enough burn to put you over the edge against heal priest or controll warrior  

cosmic anomaly- i feel like most people forgot this card is in the standard rotation. I think this card has won me more games than any other card in the deck

Mulligan: Keep any 1-3 mana cost minion, flameward vs agro class like paladin or shaman any elemental if you have evocation. Only keep frostbolt against priest so you can kill cleric for the same reason mulligan away thalanos against priest. keep intelect only if you have invocation+ elemental. if you have secret keeper keep ancient mysteries, don't keep any secret she'll most likelly die before turn 3.

replacements : luna and siamat are must haves go play another deck if you dont have them.

you can replace thalanos with leroy, loot hoarder, zilliax whatever u think u need

if you don't have keysmith just play some secret
