U. B. Herohill is my first choice for fun, followed by Andromeda.
Herohill has 3 great houses with fun cards. Tireless Crocag just wants to fight. Gabos Longarms wants to fight but not really you. Overlord Greking wants your creatures but just the weak ones. Solid Sanctum to hold things together. Arise for pullback of what you need. Solid Brobnar cards to give everyone a good time.
Andromeda Is similar but different shenanigans. Ember Imp, Drumble, x2 Foggify, Anomaly Exploiter, Replicator, Bulletyee, Asp, and many more.
