1st thing to do is to use Sylvia (heidemarie's partner) linking both the softie and Ross radiant flow

Sylvia

1

Radiant Sword Flow

Skill

[ Unique ]

Increase Damage Amount of this unit by 15% for each Justice Card in hand for 1 turn (max 75%)

Basically, you use this as the 2nd last card which discards the softie so that the flicker card combines without any hindrance and the X flicker epiphany version can have the move exhaust card from discard pile to hand divine for the softie to comeback on hand the next turn so you just repeat this cycle every turn.

X

Flicker Blade (Unbound)

Attack

[ Light Dark / Unique / Finale ]

400% Damage

+120% base Damage Amount for each X

On polarization, split into Shard:Light (Unbound) and Shard:Dark (Unbound)
