Haha, the things I find fun are sometimes refereed to as “Anti Fun” I really like winning the long race by being completely absolutely ahead of the opponent when they have no chance of winning. The early game is always rough, but if you can survive without being to far behind on board these decks win the late game. All of them have a decent amount of healing and don’t rely on burst except the Vanar one. The decks I have that try to accomplish this are:
Ultimate Control Vaath- Heal 20-30 HP everygame while removing every threat. Emerald Rejuvenator, Earthsphere, Alcuin Loremaster. Win by drawing out the game till your opponent is topdecking. Smack them in the face 2 times to kill them.
Note the reduced cost of my Earthspheres(2/3/3) I could heal 24 HP in one turn if I wanted to, AND THEN BBS. Fun fact, you CAN NOT under any circumstance out heal Ghost Azalea if you don’t have a way to ping off charges.
Arcanyst Lyonar/Vanar/Abyssian- Prismatic Illusionist/Owlbeast Sage combo to flood the board. Lyonar buffs minions(Plasma Storm counterplay) and self heals ungodly amounts. Vanar has burst through Polarity and Aspect of the Drake. Abyssian has Keilano, wraithlings, and best cheap spells to spam.

Artifact Argeon- Heal stall until you have artifact combos. Arclyte, Dawns Eye, Grove Lion. Strong against decks/factions that don’t have ping or artifact destruction.

I really like healing, especially with how popular aggro is. Against the more aggressive lists, if you can heal 10-15 HP you pretty much win unless they have godlike card draw(Trinity Oath I am looking at you)
If you want to see any of the lists let me know and I will post them.
