Post Rotation Playsets

Just a note, as for the lands they will be facing stiff competition from the Mirrodin Beseiged block lands as well as from the X edition pain lands for modern play.  None will see any play in legacy.  All will see play in EDH decks.

Cards I believe will see play are:

Restoration Angel - Sees play in Modern in kiki-Jiki pod decks since it infinite combos with Kiki

Bonfire of the Damned - Really just too slow. EDH doesnt want it cause it only hit 1 player and Modern and Legacy have better uses of mana

Terminus - This sees play in Legacy Miracles and with things like Brainstorm and Top, this a really safe bet to hold value. Tucking in EDH is huge too so solid card there.

Entreat the Angels - Same as Bonfire. Just too slow and there are better options in EDH (Decree of Justice).

Falkenrath Aristocrat - People love tribal and this is one.

Geralf's Messenger - Really heavy on the mana cost and there really isnt a mono black control deck yet that would make this take off. Im not hating on this but I just dont see it any where.

Geist of Saint Traft - Boggle Auras in Modern and U/W in Legacy use him. Hes legendary to so EDH like his commander status. Really anything with Hexproof is a win.

Gravecrawler - zombie decks, mono black control, B/G speed (risk - 2/5 personal belief, otherwise 3/5) - Agreed

Liliana of the Veil - any deck with black (risk 1/5, already sees legacy & Modern play) If you can get her cheap you should

Huntmaster of the Fells - May see some play in Modern Jund Builds but not really anything else.

Other Cards
Innistrad-
Olivia Valderan - More than likely to see play in modern but good in EDH
Grim Grin, Corpse Born - Really good EDH General
Garruk Relentless - Planeswalkers are always casually popular.
Honorable Mention Non- Rare -Invisible Stalker - Really strong card and sees play in both modern and EDH.

Dark Ascension -
Thalia, Guardian of Thraben - Sees alot of play in Death&Taxes
Mikeus the Unhallowed - Good in EDH cause he Combos with Triskelion.
Sorin, Lord of Innistrad- See Garruk Relentless.
Honorable Mention Non-Rare - Lingering Souls. Sees play in Modern Soul Sisters and Death&Taxes.

Avacyn Restored
Avacyn, Angel of Hope - EDH POWERHOUSE. Play against her and tell me shes not annoying as hell.
Any of the Powder Puff Girl Angels (Gisela, Sigarda, Bruna) - Super strong and Great EDH Generals in their colors.
Griselbrand - Omini-Tell and Sneak and Show decks in Legacy love him.
Tamiyo - SEE Above
Vexing Devil- Has ALOT of Potential in Red Decks.
Craterhoof - Token Swarm in EDH is a thing. this guy wins that race.
Honorable Mention Non-Rare - Blood Artist - Used alot where Gravecrawler is used.

A couple of these already see some modern and legacy play but others Im not to fond of. Since you kinda hit major ones Ill just give my opinion on them.
