I own over 20 commander decks and Cyber Monday is a great time to get into the Magic: The Gathering format with these deals

pcgamer.com:

Okay, I lied. I actually own closer to 30 commander decks but saying that out loud hurts my wallet a little. Commander, the singleton Magic: The Gathering format where you build 100 card decks around a single legendary creature called your 'commander', is perhaps my favourite format.

However, part of the problem with it is that it can get quite expensive. I regularly show up to tables where players play single cards worth more than my entire deck. This is why one of my very favorite things to do with the format is play with budget and/or preconstructed decks. When choreographed, I've found most tables have a good deck to match you. This Cyber Monday, there are a few great deals on precons that are both strong enough to rock up to most tables and cheap enough to not spoil the love you can find in an otherwise fantastic little card game.

Magic the Gathering Modern Horizon 3 Graveyard Overdrive | $69.99 $34.99 at Best Buy (save $35)
Graveyard Overdrive, as the name implies, is all about playing around with the graveyard. It has a subtheme of summoning the Lhurgoyf creature type, and using all that graveyard power to mow down enemies. The Lhurgoyf theme is a little underdeveloped here, explaining why it's not as popular, but it's still loaded with good cards.

Modern Horizons 3, the set that this deck comes from, is one of the most premium Magic: The Gathering sets of the last few years, and the MSRP reflects that. The two Modern Horizons 3 decks we've highlighted are the least popular of the 4 from this set but this is still a great deck that can hold up even at tables with custom-constructed decks.

Being black, red, and green, this deck is all based on sending your own cards to the graveyard, and then pulling them back out to swarm your enemies.
