Ya, trying to build up a competitive modern deck. Starting with chaos while it's cheap but after that it will be onto untamed and dice.
I made the mistake of buying a lot of gold cards last time but only got them to level 7 because of the cost. Now that I want to play at champion it's fully regular cards maxed out for the plan.
I do have a second account that is just for renting and that money is going into the more expensive cards like legendary and gold for more rentals.
