For this added cost, you get a ton more value, as Sephiroth can easily draw you a card upon entry
There are a lot of new cards from Whispers with on-play abilities that target a chosen character, so we really do think Ward gains value
The other is if a player runs out of cards in their deck
The hero and villains throw around draw three cards, reanimation, scavenging your opponent's graveyard, stun counters and discard payoffs
With the right deck, and maybe some plays with You Came Back, you can get some incredible turns going, driving up those Lore counters and taking out some of your opponents characters
Cards like Blood Tithe are perfect to give you a quick burst of life
