Miss this version recently?some long-forgotten cards
I like fatties, and test a lot of them. When you say "too much" do you mean too powerful? I don't think Elesh Norn is too good. Here's a couple I didn't see on your list that I like:the difficulty i'm having is finding the right fatties
Bloodfire Colossus
Maelstrom wanderer (I know it doesn't reanimate well)
As far as your list goes, of things I've tested to some extent:
Akromas were both highly annoying with their protection/clock+wall.
I've played with both angel and rider, players don't seem to particularly care but exile is strong.
Artisan sucks since it's a cast trigger.
Hellkite is sweet but kinda boring.
Damia almost never gets played, but when she does she's unbelievable.
Demon sucks; getting greedy is as memorable as getting thousand-for-oned.
Elderscale wurm is just green platinum cards that I see you don't like.
I like elesh norn, very powerful.
Grisel is the 'top dog' black creature in my list.
Screw shroud. (inkwell)
Iona is just boring.
Same for Jin
Ked Levi is extremely narrow... never found a proper home.
Battlesphere does fine on its own and quickly became a favorite in my list.
I've tried both platinums and stuck with angel after the big boy was near-impossible for too many decks to kill.
rune-scarred demon and sphinx of uthuun Are both in my list and do fine, flying fatties close games fast against a lot of decks, and they're still sweet to reanimate early without being as crushing as Akroma or something.
simic sky swallower is a house, same deal as above but harder to kill.
