If I take my opponent's sonic assault with with theif of Sanity and control 2 Goblin Electromancers, can I cast the sonic assault for 1 mana?
No, this doesn't work.Thief of Sanity's trigger allows you to cast the cards it exiles as though the mana you spend to cast them was mana of any type, but this doesn't change the card's mana cost in any actual way. (Yes, I know that Magic Arena shows these cards with their costs fully in generic mana, but that's a lie.) Sonic Assault still costs you 1UR to cast, and your Goblin Electromancers can reduce that cost by the generic component of the cost, i.e 1, making the total cost UR which you can pay with any mana you like.

Does Goblin Electromancer reduces the Replicate cost of Pyromatics ? Have a nice new year and a late but hopefuly nice christmas
Not in the way you want it to, sadly.When an effect reduces the cost of a spell, it reduces that spell's total cost and not just elements of the cost. This means that Goblin Electromancer will reduce the total cost of your replicated Pyromatics by 1, and not by 1 for each copy of it. For example, if you want to cast Pyromatics and replicate it twice, Goblin Electromancer will reduce your total cost to 2RRR and not all the way down to just RRR.

Spells decks tend to look to cards like this for inclusion in their decks. Decreasing your spells costs by even one can quickly add up, especially when you do a little bit of ramping yourself. Drop a few mana rocks, maybe get some extra lands or make some Treasure, and all of a sudden you’re going to be casting a whole lot more spells with one of these bad boys on the battlefield!
Of course, you’re most traditionally going to be playing this in a spellslinger deck. Decks like Mizzix if the Izmagnus and Kess, Dissident Mage are especially potent in with a card like this, further discounting your spells in the former and discounting the spells in your graveyard in the other. If you want a more aggro approach, however, slide this into Kalamax, the Stormsire and load your deck up on instants.
There admittedly is not too much to say on this card. Its effect is straightforward, as is its practicality. A lot of people call this card a staple in the format for a very good reason, especially in those spellslinging decks.
