Hello! Sorry for my english, I'm from Poland so I'm not so good in it :P I buy bunch of standard pack, so i have now 1600 dust, and I dont know what to do. I must choose around 1x Finja or 2x Gentlezaur and 2x sea giant in murlock deck. Replace for 1x sea giant - i have deathwing, sooo i dont know. 

Can you guys help me? Thanks!

It would be best to continue saving your dust to get both Finja and Gentlezaur.  You can play murlock without the sea giants.

I think the first priority would be to take Gentlezaur before Finja though.  Gentlzaur makes all your murlocks betters, whereas Finja just pulls some out of the deck.  He is a lot of fun to play though.  Tough choice!

Gentlesaur is better than Finja in Shaman Murloc deck.

In Paladin murloc deck Finja is better with Spikeridged Steed.

Depends which class you are playing.

What class do you want?

Given your bad English, I don't know if "murlock" is specifically "murloc warlock" or if it's simply a misspelling of "murloc". 

If your opponent has no answers to deal with board then finja looks to be good - my guess

and if you want to clear opponent board then megasaur will adapt your minions with poison(may be) then megasaur is perfect.
