Conjurer's Closet was a blast on the prerelease tournament with it. Dude went up to 120 life!
aside from that, anything that blinks it, together with some tokens/cheap creatures, would give you a lot of life.
Any player that has been around since the early days of MTG probably has a great deal of nostalgia for this card. The reason for putting this card in your deck is so that you can say you killed your opponent with Grizzly Bears.
Probably pretty lame, but a fun deck to screw around with would be to just have as many bears as possible. bear cub, runeclaw bear, and cards like grizzly fate can just swarm over someone with bears. pack in something like naturalize can give the deck a wee bit o tech to deal with pesky stuff. Its not all that effective but its simple and fun to do a bear vs bear battle.
Those two are just a couple examples I could think of right away, plenty more to choose from, but I definitely feel like it wants between 4 and 6 of these type of effects since it is awfully easy to chump the large bonehoards/mortivores w/tokens or some other small things.
I agree with the above poster about the creatures after wrath...I think blinkmoth/Nether Traitor/Bloodghast are the best for this since they are the ones most easily used/they can be recurred multiple times (in bloodghast/traitor's case at least) plus blinkmoth has a pretty low opportunity cost here. Also agree about Undercity Informer ... a great card to set this deck up.
Traumatize is probably pretty good (as a 1 or 2 of...we want to keep creature concentration pretty high for our game-plan), but remember to cast it on yourself if you absolutely do not know what your opp. is playing (since they may be creature-less or have just a couple utility guys.
Golgari Grave-Troll would probably be a good fit for this since he acts sort of as mortivore/bonehoard 9-12 while helping to fill your grave and being a recursive beater.
Throw in a few sweepers (they should be extra good since most of your creatures can be recurred) and you should be good to go.
Have a helicopter drop you off out front. Light your cigar with a small Indonesian boy holding a black lotus. Then bust out a craw wurm deck with no sleeves. Raw dog shuffle, loose terribly, flip the table, leave in a hovercraft.
Ah yes, an old favorite and a near-staple in goblin decks. It's expensive casting cost makes it a crap choice for the average goblin deck, which tends to run more 1 and 2 cmc goblins than anything else. But it's ability as well as its ETB effects make it a game changer at the least and a game ender at the most. I run it in my Krenko Strike deck and see much use out of it. Usually, I either Goblin Lackey one out turn 2, dump it a turn or two early with Goblin Warchief/Skirk Prospector, or secure it for the kill with Goblin matron/Goblin Recruiter/Goblin Ringleader. It is by no means the win condition of my particular deck, but it certainly helps with reach. His ability has a nice synergy with Goblin Sharpshooter too.
