For the comments section:
As to whether there are still modern opportunities. Look to Modern Masters 1. There are quite a few 1-7 ticket cards that are still hovering near their low, but are bound to be used in modern. Even if the cards are used in fringe decks, you’d be surprised how many modern players like to play fun quirky decks over tier 1 proven decks. Never mind that the field is somewhat wide open for the formation of a new meta after the bannings.

I personally don’t believe that any Modern Masters cards will be reprinted in MM2015 (with the outside possibility of Tarmo returning). If I’m right, this means that demand for the staples found in this set will be in high demand with renewed interest in modern, Feb-Jun with protour Fate, Mocs, mm2015 release.

The downside to MM investing on mtgo is that Wizards can call up flashback drafts whenever they choose and MM is a popular one. They might even decide to do combined events with MM and MM2015 online in May. So keep this in mind, and keep your eyes and ears open for announcements that will affect your positions.

I like these at their current goatbot prices. And I have positions in all.

Kataki, War’s Wage
Bridge from Below
Slaughter Pact
Summoner’s Pact
Maelstrom Pulse
City of Brass
The two Swords
Elspeth
Vedalken Shackles.

As Brecht Van R suggested, from a speculative point of view, and talking about all Modern cards in average, the best is to wait until MMA2015 release events. By then, I would expect most of the Modern cards to be fairly lower than now.

All reprints should lose a big chunk their current value and the Pro Tour/MOCS feel will have passed.

Most of the best opportunities have passed with the B&R list announcement.

If you have followed the two first MTGO Market Reports you have hopefully bought some god Modern positions. We’ll discuss the few remaining “good deals” in the MTGO market report tomorrow. But there’s less and less.

Although the upside may not be that great I like Grim Lavamancer at 2 Tix. In the same idea Sower of Temptation is now slightly under 4 Tix and on the rise. I’m not sure about the relevance of this faerie in Modern but it previous record in September was 8 tix. I bought several playset of Sower ~3.2 Tix expecting something around 5-6.

Then there are few “why not?” bets that can be done. Bitterblossom? Chord of Calling? Sulfur Falls? These could yield some profit but also have chances of not being played at all.

I would indeed wait a few months, maybe even wait after modern masters is being drafted, because there were certainly be cards that are interesting for you.

You can take the time to decide what deck you want to play and if you are not used to MTGO, try to know the client, learn the tips and tricks. It’s really important if you don’t want to lose games because of client crashes, bugs, time outs, accidently pressing F6, not selecting the right times to demand priority,…;

I have the feeling it is, and I’m glad with a small set of cards I invested in, but this article indicates that there is still some time to invest in modern. Is that right?
