Won't work because your totem wouldnt stay frozen because it never attacked.
I'll be honest, I didn't know it worked that way. Freezing my minions on my turn is something I usually don't do. I guess there's that 1 in 4 chance you get Searing Totem and are able to attack with it before freezing it. Then you have to hope your opponent can't kill a frozen 1/1. It's not happening is it?
Too bad it's not 8 armor per minion, that would Shatter freeze mages' hopes and dreams for good lol. Too bad other classes don't have freeze to (except Shaman, but it's never used), this way it will stay a niche card.
Though, yes, Frostrider comes into mind if you're using taunt minions and play defensively.
This minion is useless really. Like even Gentle Megasaur without any murlocs in your deck or Chillwind Yeti would be better. The card text if it said 'if one of your other minions is hexed or polly morphed' it would be better than this
