i'm very sorry, i'm new to this site too. How do i erase this threat?

I'm new to t1 and i started to browse around for decks and meta, i saw that the deck with goblin welder, sundering titan and mindslaver was very dominant, as were other decks, but i was intersted in this one,  can anyone tell me how good is this deck and if this would be a good deck to invest as my first t1 deck? I know Fish is one of the cheapest decks and it does very well but i think welder is better. Any suggestions?

this is gonna sound odd,  and maybe i'm posting it in the wrong forum, but can anyone tell me where i can learn how to make a web site like this one? i need to know where i could get the tools and some manuals. I don't care if is free or if i have to pay.
