Awakening .

Helm of Awakening and Arcane Melee ?

I keep, like, quadra-posting, but that's because I never remember everything at once. Sorry about that.

Hunted Wumpus ! And also Hunted Troll and its ilk.

Upwelling seems good for keeping everyone happy.

Heartbeat of Spring is a good group hug card. Off topic here: do you plan to add a resource for card draw in EDH?

I'm thinking about one for draw power. I'll start brainstorming and see what I get.

Prosperity needs to go either in here or with Skyscribing in card draw.

Boldwyr Heavyweights , same idea as Hunted Wumpus but they can search their library.

2x Jace Beleren ?

Zhur-Taa Ancient is missing.

The tempting cycle from the new commander decks, I feel they should be in here also. Given the description, they help all players and heavily political.

Noble Benefactor is pretty nice. Flux and Pyxis of Pandemonium too, maybe?

Prosperity is listed twice FYI.

All the tempt cards:

Tempt with Glory , Tempt with Discovery , Tempt with Immortality , Tempt with Vengeance , and Tempt with Reflections

Hivemind? Every one gets everyones instants and sorceries, Wild Evocation? Make a random spell happen for every person playing at the beginning of their upkeep.

Some selections from my own group hug deck which aren't listed here.

Forbidden Orchard , Vision Skeins , Unifying Theory , Planar Birth , Charmed Griffin , Heartstone , Noble Benefactor , Anvil of Bogardan , Weird Harvest , Truce , Iwamori of the Open Fist , Reward the Faithful , Words of Wisdom , Indentured Djinn , Walking Archive , Vernal Equinox

Dictate of Kruphix

What about Hunted Dragon , Hunted Troll , Hunted Horror , Hunted Lammasu and Hunted Phantasm ?

Spectral Searchlight
