Best angle of all: retirement
Anyways I haven't played Magic in years. (since shortly after Guildpact was released) Never played tournaments or anything really besides of a draft here and there, mostly played games with multiple opponents, so the deck I played most was a mono black built around subversion.
Was recently thinking of buying some cards just for the hell of it, perhaps collect a little bit since I don't know anyone that plays where I live now.
(I quit when I was having the best luck getting Foils for some reason, got a foil Birds of Paradise from Ravnica shortly before Guildpact released, and a Foild Angel of Despair on the day of the Guildpact release, doubt they are worth much of anything now though.)
Birds are evergreen; they may not be worth MUCHO $, but they'll always be useful. You seem like the type of person that would enjoy Commander format, or as it used to be known, EDH (Elder Dragon Highlander). The point of the format is to put fun over competitiveness, though there is a streak of that left in it. It's meant for social groups. The idea is that you build a deck of 99 cards with only 1 copy of any non-basic land card. You also pick (most) any legendary creature as your "general". Your deck can only contain colors that are found on your general, for for example if I were to pick Momir Vig as my general, I couldn't use Angel of Despair in my deck. Anyway, games are usually multiplayer and you start with 40 life. Play proceeds as normal with a few differences:
1: Your general starts the game in his own little "removed from game zone" face up. You may cast it from here. If it is removed from play, you have the choice to move it back to this zone (example: if it's killed, you could move it back here instead of into the graveyard). Each time you cast it from this zone, you pay 2 colorless mana as part of the casting cost for each time you've cast it from this zone before.
2: If anyone takes 21 damage from any single general in the course of the game, they have lost. Some people pick generals with an aggro slant for this reason.
I'm probably forgetting something else, but these are the main sticking points of the format. Take a look around your area and see if you can find a group to get back in the game with; the game is on an upswing of popularity again, so it's shouldn't be too hard. Start with some casual games and maybe a draft or two to get back into the swing of things.
