Death and Taxes in Standard is now a possibility because of this little annoyance named Tithe Taker. The card not only pushes your opponents back for one turn, but it also has Afterlife, as if the taxing ability wasn't enough.
Orzhov and Mardu Token lists will definitely want to have a full set of Tithe Taker. But other decks that run white humans would want to include at least two copies of it for ruining opponents' single-target removal spells and AoEs.
Some of the control decks would surely benefit from a few copies in their sideboards as well because it contests against other control match-ups.
