I like the water life idea the most. I suppose you could do something like this
Water Mark
12 Life pendulum
5 Nymph queen
6 Forest spirit
2 Ice shield
2 Druid Staff
3 ? Maybe ice bolt/freeze
That should allow you to take advantage of the synergy between life and water with your forest spirits being able to do high damage from buffing themselves and being given adrenaline by the life nymphs you'll eventually create, while the druid staff and ice shields buy you more time to set up your buffed spirits.
You could also do water/aether and make yourself immortal nymphs with 7 attack (that is, if they survive one turn to use their ability the next turn), while also combining mind flayers to provide you with a large amount of creature effect removal, and lightning for creature control. Additionally, the flayers could be used as bait for CC while you set up for your nymphs.
e.g
Water Mark
12 Aether pendulum
5 Nymph Queen
4 Mind Flayer
2 Lobotomizer
4 Lightning
3 Phase Shield
Just some ideas. Hope they help.
