>Persian Bubble Beam vs. Rhydon: 231-272 (55.9 - 65.8%) -- guaranteed 2HKOStarmie and Blissey both also deal 1/3rd - 2/5ths of Tauros' HP off of Blizzard, and nothing else in the tier can switch in, bar Lapras and Slowbro. But that freeze chance is what makes it absolutely the best coverage, since you can turn a check into a momentum drain and win.
