I enjoy playing permanents in my M:TG decks, certainly much more than playing one-turn-only spells–I like game effects that continue on past one turn, that help me build up strength, life points, etc. The following twelve cards help me toward that long-term-survival goal:

Angelic Chorus: Finally, a reward for playing the creatures with huge toughnesses! Indomitable Ancients, anyone?	Boon Reflection: Because gaining single-digit totals of life is paltry. 😀
Pristine Talisman: Hmm, tap it to not only get a mana, but gain a life. Fun with Well of Lost Dreams. xD	Quiet Disrepair: This is one of those cards you can use to destroy your opponent’s enchantment or artifact, or use on your own stuff to gain a free 2 life every turn. It’s a win-win!
Scourge of the Nobilis: Firebreathing and lifelink, together in one creature enchantment!	Shield of the Oversoul: I admit it: I play this because of the indestructible ability. Makes Green stompy creatures that much funnier.
Steel of the Godhead: The combo of lifelink and unblockability is AWESOME.	Story Circle: Because the Circles of Protection, as cool as they are, are only situational. THIS one covers the board.
Sun Droplet: Because it’s hilarious to watch your opponents grimace as you get back all the life points they knocked from you, one turn at a time.	Test of Endurance: I love this win condition so much I have a deck built around it.
Wheel of Sun and Moon: The #1 way to survive a mill deck’s onslaught. Also funny in a deck that draws a lot of cards–this way, you don’t accidentally deck yourself!	Worship: Just never block with your last creature, and make sure you have a way to quickly put out another creature on the fly, and you won’t have to worry about dying from combat damage!
