Also grim guy is excellent versus Strix, maybe versus DnT creatures without mom protection. Right now i use Fatal Push and Decay against all of this threats, but maybe Lavamancer is just a better option.

He can be very useful in situations where opponent countered all of your spells and you both in topdeck mode - when Lavamancer is a clock and another corner of the attack. The corner that your opponent can not expect.
If the mana investment isn't too much of a problem for you Pack Rat may be a better option. You might run out of fuel for Lavamancer's effect especially if it doesn't come down early and an opponent becomes aware that you're running it and you always have to wait a turn to activate it. Pack Rat can win the game on its own, can help you bin fatties and dead spells, and can be activated the turn you jam it if you happen to have the mana/Dark Ritual.
