Help Toph First Metal Bender Deck

Hello I am building a deck for friend with [[Toph, the First Metalbender]]

$1000~, Bracket 3. Looking to build more artifact focused and getting value from re using them. I am struggling to find a definitive wincon. Is it just +1 counter creatures and combat? Anything else I can add to spice it up more and speed it up?

Recommendations for some cards and cuts would be great. Also share decklists and gameplay lines if possible?

Appreciate any help there is. Thanks!
