Need help! Freeze controll Raikka.

[Ice1989]

Hi everyone!

After being gone from the game for about 6 years i decided to reinstall the game and have another go at it.
The deck i built is quite consistant and does what i want it to do, (more or less.) and i wanted to ask you guys for some tips / tricks to make it a bit more competative.

*update* i reworked the deck with Amaria and it got a lot stronger and consistend.

Freeze controll mage:

Hero: Raikka Spellseeker (40 cards)

Ally (18):
2x Frostflame Harpy
4x Popsickle
2x Death Mage Thaddeus
4x Stalactitan
4x Frosted Urigon
2x Forgotten Horror

Ability (8):
2x Shriek of Vengeance
3x Contemplate
1x Shriek of Revulsion
2x Transmogrification Curse

Item (13):
4x Tome of Knowledge
2x Urigon's Fang
4x Living Ice Wall
3x Voice of Winter

Deck Code: 733146B

1 of its weaknesses is weapon hero`s and rush/spam. If anyone has some pointers for me id apreciate it greatly!

Thanks in advance.
