Well, lets try again: druid+ffq+blossom+feral bond seem to be quite a good combo.
1. You can drop a permanent creature factory on your side for cheap (3 life all you need, you can do this on round two if you got just one pillar and this card).
2. These creatures grow their defense each round, therefore they will be unremovable (by your opponent) in a few turns. Unless the opponent dropped an Oty fast enough, they will outgrow the oty for free.
3. These unremovable creatures power your feral bond. Once the bond is out, you gain an increasing amount of healing per round, until your board is full (If you need board space, you can sacrifice the creature, unlike with cells).
4. If you need some rainbow quanta, break one of the appropriate. (Druid, Firefly Queen are obvious choices, i didn't go through all the cards, but definitely there are some useful choices with good life synergy).
5. And on top of all this, you even get some extra healing, so you can drop the healing cards from your deck, good, because you have to put the druid and ffq somewhere.
All i said, to consider remove point 5.
