Check my list, it seems we came up with similar ideas. Gisa, Prom Queen

Rings of Brighthearth

Phyrexian Dreadnought gives you 12 zombies for 1B.

I'm trying to come up with my own Gisa EDH. It's a rough first draft, but here it is in case you can get any ideas:

Ghoulcaller Gisa's Zombie Brigade

Also, I was considering Dark Prophecy for my deck as well, but if you have a lot of zombies and someone plays a creature board wipe, you will be in some serious pain (my group is heavy on board wipes). Just something to keep in mind; it's still a great card for this deck.

@ProgenitorX I am well aware of Dark Prophecy 's drawback. I was hesitant to add it (because my neighbor has a dickish Sharuum deck that's pretty much just boardwipes and counter spells,) but it has paid off for me. I was also considering adding Blood Artist Keep me alive.

I know Phyrexian Dreadnought is great but it's a bit pricey for me. (Just added Phyrexian Obliterator a couple hours ago. So i'm broke. It also can ruin my day if they kill Gisa in response to the Dreadnought being cast, especially early game.

I'll give your deck a look. I love giving advice, especially on Gisa (who already I've played enough to know what's good and what could be better) I'll look after work and Offer suggestions.Thanks.

Thanks! I've already gotten a few great additions from your deck (Thornbite Staff ). That's a good point on the Dreadnought. Maybe I'll reconsider him, especially since he costs quite a bit to buy.

@ProgenitorX Like Dreadnought is amazing in theory, but if it back fires it'll wreck everything. I'm playing a more control-y build, trying to not let my opponents have any creatures but I still have yet to go up a competitive deck or the Sharuum deck. It's dominated so far though.
