On Yzard, I like having a physical coverage move, and have been running brick brick because...
4 Atk Mega Charizard Y Brick Break vs. 252 HP / 4 Def Blissey: 462-544 (64.7 - 76.1%) -- guaranteed 2HKO after Leftovers recovery
I like catching a predictable blob on the switch.
Thing is...
4 Atk Mega Charizard Y Brick Break vs. 252 HP / 0 Def Heatran: 108-128 (27.9 - 33.1%) -- 85.4% chance to 4HKO after Leftovers recovery
Which is frustrating, especially since I don't run Focus Blast, opting instead for hidden power ice.
And so I considered earthquake because...
4 Atk Mega Charizard Y Earthquake vs. 252 HP / 0 Def Heatran: 284-336 (73.5 - 87%) -- guaranteed 2HKO after Leftovers recovery
but...
4 Atk Mega Charizard Y Earthquake vs. 252 HP / 4 Def Blissey: 308-363 (43.1 - 50.8%) -- guaranteed 3HKO after Leftovers recovery
now, don't call me greedy. A 3KO on specially defensive blissey is awesome, but I don't want to have to deal with softboiled or a toxic or thunderwave, but I know that, and especially for my Yzard in particulary, Heatran is the greater threat.
But Heatran often runs air balloon, which weakens Equake's case even more.
Any suggestions as to what I should run?
