I love this deck type. I was trying to make a deck that revolved around the Life nymph and came up with this
5c5 5c5 5c5 5c5 5c5 5c5 7ac 7ac 7ac 7ac 7ac 7ac 7ac 7ac 7ac 7ac 7ac 7aj 7aj 7an 7an 7an 7b0 7b0 7n2 7n2 7n2 7n2 7n2 7n2
Exact same strategy - you can effectively make sure your opponent never damages beyond your ability to heal by using the Spine Carapace and adrenaling his/her monsters. Giving a creature multiple attacks versus this shield is practically a death warrant and the healing supplied will always make up for the extra weaker attacks.
It can be used as an FG deck but fails miserably in a few conditions.
1} Gravity, Dissipation, Fire Buckler, Spine Carapace, Diamond, Permafrost and Jade shields all kill this deck when played.
2} Steal is used while your own shield is up.
3} Poison type creature control is used.
The dragons would solve some of the shield problems but aside from that I'd think you're running into the same loss conditions as me.
In order of easiest first the deck can beat;
Ferox
Divine Glory
Paradox
Osiris
Dark Matter
Destiny
Fire queen
Seism
With dragons Elindis and Miracle should become beatable.
I'd say this deck is more a Halfblood killer deck rather than anything else, but it's just great fun to play
