Honestly, Anivia is annoying to get. I don't understand why Brand comes out so much more compared to the bird. The plight of the "Herald of Frozen Death" build is that it is completely LATE game with HIGH cost in both gold and enduring losses. It takes a long time to get units and even longer to tier them if you ever the chance.

I have had my share a losses by simply not having enough health by the time I get anything going. Its pretty painful at the beginning.
I have been completely annihilated by wild/brawler(the f'ing knockups), assassin/blademaster (everyone body one/two-shots all your units), noble/blademaster (healing circus), or noble/sorcery combos since forever. Especially when they get Yasuo, Aurelion, and/or Karthus (ffs).
By no means is "Herald of Frozen Death" unstoppable when it is incomplete, outnumbered, and/or undertiered.

But, boy does it feel good giving everyone the middle finger when it works.
And no, Lissandra is not useless. She is especially useful for freezing the enemy backline which is always hilarious. Even better when she pulls assassin leaps then freezing herself with AOE damage, and buying time for the rangers to finish killing whatever they are shooting then turn around and kill the assassin. She is not suppose to be Veigar or Morgana with ice.
