Megrim kind of sucks and usually wastes a spot in hand destruction decks. Those decks always had a problem winning for me in general... just didnt have a good win condition once I had my opponent's hand emptied.
That's the beauty of a control deck. You don't really need a win condition. You get your opponent with no cards in hand. He draws one a turn. If he doesn't play it, abyssal specter takes it on your turn. You pack enough removal to kill all his creatures (or at least fliers). You're basically just bleeding him slow. Buuut if you want a win condition...you're playing black. Take your pick. No shortage of big, ugly stompers.
My favorite deck revolved around blue/black reanimator control. Turn one, careful study (or entomb), pitch spirit of the night or some other fun thing depending on what kind of decks everyone else was playing, turn two exhume it.
Tricks with the graveyard were always a good time. I miss Odyssey.
I also miss U/G Madness. That was just fuckin' fun to play.
Or I'd go out in left field with a 7 (or 8 maybe) land green stompy deck, that would fairly quickly overwhelm the other side.... Mostly one mana 2 power creatures, or creatures you could cheat into play for free, land grants and elvish spirit guides for that extra mana burst. Could literally run you down before you even had time to play a wrath... and opponents chipping at their own life totals with pain/shocklands... good luck.
Do you remember Tooth and Nail? I played the version with Urzas, never really got the cloudpost one. Good times.
I don't think it's really broken anymore, with the current state of the game being so creature-oriented. It may be really powerful, but I don't think it's inherently broken anymore.
It's definitely ahead of the mana curve. Pack 4 of those in a deck and the other guy doesn't have a chance. 4 Hymns, 4 Ostracize, some Abyssal Specters...unless he's playing Goblins of White Weenie or some shit where he can flood the table with creatures before you blow up his hand, he's fucked.
Yeah, that's pretty awesome. My inspiration for using Megrim was actually the fact that I had a bunch of people tell me it was shite tbh. I'm the kinda guy that likes to make decks that found ways to make cards like that semi-decent.
It's not terrible. It's just that in my experience, a discard deck typically whittles the opponent's hand down really fast and then they don't do much discarding. The effect of a discard deck is really to limit the opponent's options, rather than simply to make them throw cards out. Therefore it'd be pretty slow to kill with Megrim. Again, it's not terrible, but those spots could be used for more effective cards...off the top of my head
4 Terror
4 Ostracize
4 Abyssal Specter
4 Dark Banishing
I'd run 20 swamps, but I'm paranoid about mana screw. You could go 18.
That brings you to 34-36 cards. 24-26 spots left. At least 6 go to discard spells, you'll want some more creatures as well. It's also not a terrible idea to run some Drudge Skeletons or something in case they get creatures out and you need a blocker. You'll also want some more removal, probably. And of course a win condition, probably something big and ugly. Yyou could go for a big Corrupt or Drain Life...I always liked Promise of Power cause it offered more flexibility.
Basically, you can go a lot of ways with the deck, but there's always gonna be a better choice than Megrim.
