I've revised the deck a bit since last posting, I will track and post statistics soon.
1 elven druid, 1 improved plague, and 1 improved anti-matter have been added, and now all 6 sunglasses are not upgraded.
1 otyugh, Golden Nymph, 1 Fire Storm, 1 eternity, and 1 shard of divinity have been removed.
The elven druid adds some more diversity for creature removal/modification, improved plague is an alternative creature killing card, and improved anti-matter can be an extremely effective healing card at times. The eternity and Golden Nymph seemed to have limited use at times so they are out.
Casthegamer, while it is true that half the cards are permanents, I am mostly comparing it to more ;standard; rainbow anti-FG decks. In those decks, you will find all/any of the following: Empathic Bond, multiple weapons, hourglasses, shards of generosity, graveyard/boneyards, and more, as part of the central strategy. 6-7 types of permanents is common.
So while sundials and towers do remain in the deck, sundials are extremely low cost permanents and only last a turn so are not very permanent...
Towers are sort of a given for most decks... and I consider them in a separate class from most permanents.
Bone walls are permanents, but are very different in that they do suffer from the weakness of being stealable or deflagable.
So permanents aren't completely gone, sure, but the reliance on them for strategy and winning is greatly reduced. Now, this may likely not be the right path to take, as permanents can be very powerful. But perhaps it has potential.
