Very lucky at the end. Tips for each round: Round 1: Slightly charge Up Smash on the first Inklings, then do the same but on one of the platforms. Round 2: Spam Up Smash for damage and go for a charged one to KO Dark Samus and Ridley. Round 3: Make sure to push the Belmonts with Dash Attack, then either use Down Smash or Forward Smash to aerials to gimp them. Round 4: Spamming Up Smash is hard to considering that enemies are more evasive at this point. Round 5: Start with Neutral B and hopefully it will hit both of them, then go for Dash Attack and you can KO them with Forward Smash or gimp them. Round 6: I was very lucky on this one by using only two Dash Attacks. Other than that they are hard to KO or push them to the blast zones, so play safe and wait for you chance while they are hitting at each other. Final Round: Spam Up Smash and charge Side B when Rathalos flies away.
