"Mega Tyranitar has surprisingly proven to be a very deadly sweeper thanks to its combination of good coverage, high Attack, and insane bulk, which makes it insanely difficult to revenge kill. To put it into perspective, Scarf Garchomp's EQ only does around 79% MAX, and Ice Punch can obviously KO back. So despite its lackluster Speed stat even after a boost, the only relevant Scarfers that can reliably revenge kill it are Keldeo and Terrakion. On top of this, it also possess the same defensive utility as its normal counterpart, such as keeping Volcarona, Zapdos, and Marowak in check
"Mega Tyranitar has quickly shown its effectiveness as a sweeper. Its insane bulk and power help make up for its subpar Speed stat even after a DD, because of how hard it is to revenge kill. Its bulk also lets it keep Pokemon such as Volcarona and Zapdos in check, and potentially even use them as set up fodder. There's not much else to say about this really, as I covered a lot of its strengths in the last update, and we feel that A- is a more appropriate rank for it than B+ atm."
