Looking to spend about 100 dollars, maybe a bit more. New to making a 1v1 deck, but people at my local playgroup play it often. And the ones that play multiplayer are more casual. So even if it's not meant for multiplayer it will work well enough. Just need it to be competitive 1v1. If the cards you take out are of value then I can likely trade them. So that will up the budget of value of cards to add a bit.
Also I don't own all the cards. Here is a list of what I was already planning to buy. If you remove any of these you can add it's value to the 100 dollar limit.

Spoilered everything so when you aren't looking at the deck the post was small and fairly concise.
