The one thing that the sideaboard misses is an access to artifact (enchantment) removal but the Temur Adventures decks is declining in popularity because of its bad Rakdos matchup and the matchup is really bad already and putting couple of Knight of Autumns in your sideaboard is not really going to cut it so I am currently playing 0 but it might be easily wrong
If you dont want to go that deep, Id propose this alternate sideboard: 3 Ancient Grudge 3 Torpor Orb 2 Volcanic Fallout 1 Pyroclasm 2 Noxious Revival 3 Nihil Spellbomb 1 Emrakul, the Aeons Torn Noxious Revival is another odd one, but its easier to justify
