Looks like fun. Care if I throw together a build and try it for myself?

Aw yes, the great old school-ness that is NecroTrix! How could I forget!?!?

... I wonder if my local card shop will allow me to trade in my Tropical Islands and Flooded Strands for Underground Seas and Polluted Deltas?

C'mon! You can admit it! You all know you have some casual deck sitting arround that takes some broken card and exploits it to the fullest! I myself am in the process of whipping one up with the 4 Necropotences I just nabbed of some old guy for 2 bucks total. Hell, the Necro's came with some crap black aggro deck thats made up of nothing but Ice Age cards, but at least I got a start! But anyways, post your quirky lil br0k3n piles of jank or any ideas you may have for me to use these black card advantage monsters!

Not sure how it would work since this is just off the top of my head, but Impulse seems like it would be golden under the Helm.

... but then again, how would the required shuffle affect the deck while combo'ing out?

Ten, most definatly is perfect. Allows players like me with very limited incomes to manage the basics of a deck together while proxying the more hard-to-get and expensive aspects of a deck.
