Sweet deck! I like the aggressive group hug.

Here is some cards that maybe have a home in the deck.

Genesis. Genesis and Spore Frog is a really good combo, and it's great to get back important pieces from the graveyard.

Bala ged recovery. Most times this will just be a land that enters tapped, but sometimes it will really save your bacon.

The monarchy. I love introducing the monarchy in group hug decks. My tactic is to become the monarch, then get hit, and then NOT try to take it back. It will make it more likely for your opponents to attack each other instead of you, and they will draw more cards which is a win-con for you. So I would add a card like Court of Bounty or Regal Behemoth
