If you're talking about Modified, Stoutland is the only one that locks Supporters I believe.
If you're talking about Unlimited, you have Dark Vileplume from Team Rocket(locks everything, Items, Supporters and Stadiums) and Armaldo from EX Sandstorm added to the list. I believe that's it(a lot more cards lock Items/Stadiums than lock Supporters).
EDIT: Not sure how I forgot those, but yeah, Neo Genesis Slowking and Chaos Gym.
