Lyra, New Bruna and Kaalia seem to be the only generals with angel tribal synergy. Id personally go with Kaalia. Idk why people think it's so degenerate. Its good, don't get me wrong but there are far more degerate decks out there imo. As 3drinks said, there are ways to keep her around. Otherwise, just keep playing Sigarda or another strong angel without tribal mechanics like OG Gisela.
