They'll likely add more frost spells (though I IMAGINE given this card they'll be cheap), but the average frost spell is 3 mana. With only Blizzard and Remorseless Winter costing more. I think the hardest thing will be getting value out of both generated cards.

This is clearly a mid-late game value card. Almost every frost spell either freezes something or heals you. So they're all good control tools.

At the end of the day this is a 3 mana 3/3 that's a +2 in the late game, that's really good value.
