I brought a team with both Guardian Jackal and Justice into several Magic Night levels. Jackal has a L12 4* mana troop; Justice has a crit troop. Justice is to the right of Jackal in the lineup (not sure if that matters).
Using a yellow match-3 charges Jackal, as expected. but it also charges Justice. When I take Jackal out of the line and replace him with a non-yellow hero, Justice charges as I’d expect.
