>>22228702Almost all of these, or all of these, require a Swords Dance boost. You're implying Blaziken will be able to pull it up without the other Pokemon attacking? Or I suppose you're implying the opponent is switching. Because I'm pretty sure it will have Protect to ensure that speed boost, right? Then when will it SD safely without being attacked or crippled?
Also, something I'm curious about Gliscor since he's my designated tank. Let's take your example including Life Orb.
+2 252+ Atk Life Orb Blaziken Flare Blitz vs. 252 HP / 252+ Def Gliscor: 325-383 (91.8 - 108.1%) -- 50% chance to OHKO
Against:
0 Atk Gliscor Earthquake vs. 4 HP / 0 Def Blaziken: 276-326 (91.3 - 107.9%) -- 50% chance to OHKO
Implying it managed to set SD, it will lose the 10% from Life Orb enough to die from Earthquake if Gliscor survives. If it doesn't get the SD boost, MegaChicken 3HKOs it, not even enough to make a dent on Gliscor and resist an Earthquake AND the Life Orb damage.
