Combos Utilizing Survival-of-the-Fittest

Have both cards in play. use survival to get a big big creature in your hand. use it again and discard the big creature.use recurring nightmare to get the creature into play with no casting cost.

squee and any of these will start you off. when you use all of these together, you get an infinite source of creatures. try creatures like; spike weaver, spike feeder, ruhk egg, palincron, etc.

Sacrafice a creature to Search your Library for your favorite creature. Then Lifeline pulls that creature out of your Library with out paying any casting cost. Creatures for free!!!!!

Cast your survival. Tap as much green mana as you can to discard big creatures. Cast Living Death. Someones in trouble!

Its like recuring survival and way better than living death variant I think lifeline would work better than oath

dump loads of slivers into your graveyard and they all come into play huge and with haste!!!

use the survival to "purchase" thresh, and respond to your opponents spell with a creature, preferrably one with a "come into play ability" like mystic snake

Search your library for any creature with Survival, activiate it twice, put that card in your graveyard (preferably a Verdant Force) , bring it back into play with Hell's Caretaker

use gae's cradle to play survival of the fittest and discard all your good creatures. then use the birds of paradise to play living death. instant army!!!!!

Once the shapeshifter is in play, discard reya. Use the shapeshifter/reya to bring back the real reya. Use the survival/turbine engine to keep going through your library and discarding creatures.
