Since this was a forfeit, let me support my claim with a few calcs.
+6 252+ SpA Smeargle Boomburst vs. 252 HP / 0 SpD Mega Altaria: 372-438 (105 - 123.7%) -- guaranteed OHKO
+6 252+ SpA Smeargle Boomburst vs. 0 HP / 4 SpD Keldeo: 421-496 (130.3 - 153.5%) -- guaranteed OHKO
For Bisharp I'd have gone for Spore as to avoid Sucker Punch, then Substitute and proceeded to attack. In case of 1 turn sleep and break of substitute or if I hadn't had OHKOed, I'd have SporeSubbed again.
+6 252+ SpA Smeargle Boomburst vs. 4 HP / 0 SpD Bisharp: 259-306 (95.2 - 112.5%) -- 75% chance to OHKO
+6 252+ SpA Smeargle Fire Blast vs. 4 HP / 0 SpD Bisharp: 544-642 (200 - 236%) -- guaranteed OHKO
For the little guys
