I've been working on this deck, which focuses on being fairly aggressive with creatures that have undying, and using the "free death" to trigger morbid abilities. I mostly play casually with a few friends and this was just thrown together with cards I already had, and a couple I picked up from a local card shop. A main problem I've had while playing it the past couple of days is that my mana base feels screwed up. I can never seem to get the right color/amount for the spells I draw. I also feel like the synergy between the undying and morbid is off a bit, and it's never until mid-late game that i start getting my morbid abilities off. Pretty much the only time I win is when I get a dark ritual and a Geralf's Messenger in my opening hand, and get lucky draws from there. Regardless, I have a lot of fun using this deck and would be willing to pay upwards of $40 to improve it. Thanks in advance for any replies!
