The concept is good but execution would be difficult
alot depends on where you buy and sell it.
IF on auctions there is the buyer fee for buying it and then the reselling fee for selling it.
I is also tough to find deals anymore because of the internet and apps that make it easier for everyone to know the "Comps" on cards thus hard to buy low and sell high.
But if you do
1. stay within a pre determined budget
2. Find sites like Net54 or Facebook groups where you can sell/trade/buy to minimize the fees
3. Do not buy to much to start so you do not tie up your money in to many cards and loose your liquidity for other cards for your PC or day to day needs
4. Be prepared to sit on cards for a period of time so you do not take loses or minimize them
