Optimize a druid for debuff and healing


I would like to play a druid (preferably circle of dreams).

If possible, a wood-elf would be useful, but any race that can be tall (6ft+) is acceptable.

I would be starting level two, and probably heading until level 5 or so.

Multiclass is allowed, but not prefered.

I would like to focus on healing and debuffs, and my DM will allow a small editing of spell lists, as long as it is relatively balanced.

The party are all level two, and have a divination wizard, a assassin rogue, and a fighter, who’s archetype isn’t yet confirmed but probably will be champion.

All sourcebook and UA allowed.

Point buy/standard array scores.

Feats allowed.

(Thanks in advance, and please edit if you think it needs reformatting)
