Just got smoked by a hunter with animal companion and flare

This is the craziest deck I ever seen in Heathstone :-D

Well, that's pretty good combo. Bad match'ups are only found is Dummy Taunt Warrior (sometimes you run out of Ice Blocks) and Warlock with Soulfires and Curse of Rafaam (that directly counters ice block). But even those matchups are pretty close.

Cycle hint: draw as many Ice Block as you can. Throw away all FB.

worst matchup is loatheb and innervate

agreed, but it can't beat anything else

30-0 nothing sillier in hs I have not seen

Wait how do you even lose with this

you lose when you run out of ice blocks, if you get stuck in a situation where your last card is ice block its pretty grim prospects, eventually your topdeck won't be ice block and they'll finish you.

Either fatigue or just don't draw enough ice blocks before they kill you (having 7 fireballs in your hand looks funny lol). Therefore mulligan for ice block against warrior and probably priest, mulligan for fireball against fatigue class like druid or rogue (still might not matter, fatigue is the really the main deck that can beat this).

Running out of Ice Blocks feels bad, but it happens. Against mill decks you shouldnt play Ice Block if you have the coin, just start hitting face with Fireballs as soon as possible. I won both games I played against mill druid by living with less than 5 hp. The worst matchup would be a priest with Flash Heal and Mind Blast.

Met a Lightwell/Inner Fire priest yesterday, that was a pretty hard counter :D
