Built this when I noticed that all the combo pieces besides the optional Hero of the People were even. This has gotten me way farther in Gauntlet than the standard merchant one (but has pretty bad matchups vs. the gauntlet bosses special abilities), I would even argue it's more consistent.
Prerequisites
All combos besides the Ultimate one require Aika in the void, Reinvigorate in hand, Haunting Scream in hand.
Combos
4 power; Scream Aika + Reinvigorate + Attack: 24 damage (6/6 Berserk Double Damage = 24), to prevent
Defiance stun window
4 power: Scream Aika + Attack + Reinvigorate: 28 damage (7/7 Berserk Double Damage = 28), since it gets Reckless just after the attack
10 power: Scream Aika + Ultimate + Attack: 24 damage (6/6 Berserk Double Damage = 24)
Xo for discard bait, turning Strategize into draw 2, and Honor of Claws into draw 3.
Waystones as power because it really needs undepleted power on even turns, and without seats, Waystones are strictly better than Sigils (also Amethyst Waystone deals 1 damage for the 24's).
Remember that you can purposely overdraw to 10 cards to throw Aika into the void.
Almost always scout down.
