[fixed] Phyrexian Revoker doesn't revoke

[gnomefry]

Describe the Bug:

Phyrexian Revoker's banned activated ability remains activate-able. In the save I'm attaching the chosen source is Sylvan Caryatid. I also tested with non-mana producing abilities.

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)

Holidays 2021 ad1a6f8 - gauntlet

What exactly should be the correct behavior/interaction?

The chosen nonland source shouldn't be able to use activated abilities.

Are any other cards possibly affected by this bug?
