Unlike the other hammers on this list, Sunforger doesnt rely on combat ability, though it does have some of that via a very meaty +4/+0
Better Mid-Cost Ruby/Sapphire Deck In the mid-budget version, there are some new tools to help put pressure on the opponent
The first Zeus card to be revealed, the God of Lighting is a four-cost 0/4 that quests for two lore
For most decks, being restricted to only cards that cost three or more means that Keruga, the Macrosage has the same exact issue as Gyruda, Doom of Depths: you only get to play a single card over the first three turns of the game, leaving you in a position where you're often dead to aggressive decks (this gets even worse in older formats, which are faster and place a higher value on efficiency)
This is great for characters like Maurice, World-Famous Inventor, who will likely be exerted each turn
