Just saw this quote regarding Magic Coat in the move's thread:
Additionally, on the previous page, OmegaDonut has confirmed through testing that Probopass does indeed learn Magic Coat.
So Magic Coat can stop Taunt, Torment, Disable, and Encore; which was previously doubted. I think the worries about Taunt can be removed if a smart player uses this Probopass with good prediction.I first saw here that "Magic Coat will now work on: Whirlwind, Roar, Disable, Spite, Spikes, Foresight, Encore, Torment, Taunt, Odor Sleuth, Miracle Eye, Embargo, Heal Block, Toxic Spikes, Defog, and Stealth Rock." People at Veekun told me it was tested, so the source should be pretty reliable.
