Some #ARBBLonTour gaming, and a 3-way dance of Underworlds.
It sort of came back to me...
Gary, despite having all models removed by the end of the game, won (Skaeth's Wild Hunt) 12 vs Simon (Rippa's Snarlfangs) 9 vs Mike (Grashrak's Despoilers) 7(?).
Gary may or may not have subtlety persuaded me to go halfsies on Rivals of Nethermaze ("rats-rats yes-yes?").
Looks like I have access to 3 or 5 Rivals decks (the 2 Beastgrave starters, Rippa's and the ghouls) and the rats above.
Would have to borrow to make any S1 or S2 Rivals though.
