Got Adayu the Serene alongside Daybreak Askara, so triple multi-unite triggers means 1000 point turns, really fun. Get an extra turn with the Light Sword defeating the 7cost guy who rallies monster; after playing out the rest of the 107 card turn defeating monsters with runes and sword thanks to Remus and killing them in the void thanks to Emri for some nice looping, end the turn.
New turn starts, first card I play is an enlightened hero and... Adayu triggers, and triggers again, then Dartha suddenly triggers. It seems like the multi-unite effects have persisted into the extra turn.
