One thing I really love doing is building decks with other people's idea or testing other's decks to tweak them. If you would like, post your idea for a deck you want to make or a deck you already made and I'll "doctor it. It would help me if you let me what you want to use it for and what format you'd like it legal in. For example, kitchen table magic, Friday night magic, or Pro Tour/GP caliber lists.
currently trying to set up a flicker deck
This would be my version of flicker, considering the metagame right now.
24 Creatures4 Cathedral Sanctifier (ETB gain 3 life)
3 Ravenous Rats (ETB opponent discards 1 card)
4 Cartel Aristocrat (Power house and sacrifice outlet, this card is big game)
1 Skirsdag High Priest (Makes killing your creatures and attacking a nightmare for them)
1 Mentor of the Meak (Draw trigger triggers of off 17 creatures)
3 Fiend Hunter (Exile a creature, return it when FH dies)
4 Restoration Angel (ETB, flicker a non-Angel)
2 Disciple of Bolas (ETB Sac another creaturn, gain life and draw x where x=sac creatures power)\
2 Obzedat, Ghost Council (ETB drain 2, may exlie at EOT [your's only] and return it battlefield during upkeep, it gains haste)
13 Non-Creatures2 Cloudshift
2 Tragic Slip
3-4 Orzhov Charm (Love this one!)
4 Lingering Souls
1-2 Sorin, Load of Innistrad (Here's your Planeswalker!)
23 Land5 Swamp
7 Plains
4 Isolated Chapel
4 Godless Shrine
2 Vault of the Archangel
1 Cavern of Souls (Naming human covers 13 creatures and naming Advisor covers 6 to make them uncounterable)
Sideboard tentative and based on my meta evaluation:3 Duress
2 Blind Obedience (Very underrated, there are many good haste creatures right now)
2 Underworld Connections
1 Tragic Slip
1 Sever the Bloodline
2 Rest in Peace
2 Oblivion Ring
1 Obzedat
1 Skirsdag High Priest
Lots of cool things going on here. Playing a Feind hunter and blinking it, with the exile a creature trigger on the stack, causes the creature to be exlied permanently, so you get rid of 2 creatures at once. Orzhov charm can bring back 11 different creatures, makes 2 of the modes very good. With Lingering Souls and Sorin's Emblem (+1/+0 for the rest of the game) you can come out of nowhere and kill someone.
I really don't like the Thrull Parasites or the extort. You'll be using most of you mana every turn and with Vault you have something to do with an empty hand.
