How to build a Modern deck cheaply?

While it is not really possible to buy a Modern deck cheaply without a lot of patience, there is certainly a way to spend your money effectively and efficiently to avoid the prohibitive costs of some Modern decks. Here are some basic tips to follow as you are picking up staples for a new deck. Keep in mind that these strategies are predicated on patience. If you absolutely must play a new deck tomorrow, you will not find this information beneficial.

Before even starting to make the investment proxy your deck first. Find a deck you enjoy and want to build. It seems pretty obvious but I know so many players without a clear plan of what they even want to play. Maybe you own a few Arcbound Ravagers and want to play Affinity but also own some Noble Hierarchs and wouldn’t mind playing a green deck. Later you have a lot of money in cards and no deck.

Buy the cheap cards first 
Modern cards don’t usually get cheaper over time. Without any reprints, a card can quickly gain on value over the course of time. Take a Modern Masters set as example. When the full spoiler was revealed, the cards that were not included in the set skyrocketed. Cheap card were not cheap cards anymore. Even the commons are destined for rising prices.

Buy the most expenisve cards later
Many players start building a deck from the most expensive cards, assuming the rest should fall into place more easily. Indeed, it is true, but only if you manage to get full deck quickly, but if you know that it will take you months to complete a deck it is rather a bad decision, becasue these cards are on WotC's radar and the probability of reprint is higher. Product announcements are every six months

Buy recent reprints
If you acquire recent reprints with right timing you cannot loose money on this investment. If you are thinking of Modern in longterm it is usually a good decision to buy a playset of recent reprints, because sooner or later you will need these cards and they are much cheaper now due to high supply. Tip: Heritage Druid, Inquistion of Kozilek should be on your radar now.
