Hi there !
A deck idea that came up to my mind and one of the few that actually worked from my theorycrafts.
Mulligan for : Duel! , Prismatic Lens , Bright-Eyed Scout .
Any feedback is really appreciated and good luck trying the deck, it's super fun !
If you are going to use Holy Wrath on a turn, you might want to use it first since it's RNG dependant, and then attack with minions (unless the situation calls for another measure).
Try to use Redemption with a giant on board and not during the 1st 3 turns, because you might want to hero power for the Frost Giant on those turns.
Don't commit too much on the board with Naga Sea Witch, especially against Priests and Warriors .
Swapped 2 Frost Giants (usually dead in hand even with mana manipulation) for 2 Blatant Decoys (great target for Duel!, and usually pulls a Naga Sea Witch from your hand (having played both Bright-Eyed Scouts)).
