Vince McMahon promised to unveil the 'biggest acquisition in SmackDown Live history' last night during the Superstar Shake-up - but fans were stunned into almost silence when Elias was brought out.

The WWE Universe in Montreal were clearly expecting someone much, much bigger though and that is what they got when Roman Reigns made his grand entrance on the blue brand to close the show.

It's not taken long for the crowd to become split once again towards 'The Big Dog' following his recovery from leukaemia, but there's no doubt he makes SmackDown Live more star-studded and is an adequate replacement for AJ Styles.

He even landed a Superman Punch on McMahon for old times sake, and you have to wonder how long it'll be before Reigns is challenging for Kofi Kingston's WWE Championship.

So who else made the jump to the blue brand last night?

Well SmackDown seem to now have both the US title and the Intercontinental Championship as Finn Balor made his debut on Tuesday nights.

Joining him to boost the singles division are Chad Gable and Apollo Crews, who have split from their pairings with Bobby Roode and Titus O'Neil respectively on Raw.

After weeks of attacking the likes of The Hardy Boyz and Rey Mysterio, Lars Sullivan has now found a home on SmackDown, where he laid out R-Truth to continue his path of destruction.

SmackDown also gained a 205 Live star in Buddy Murphy, whose six-month reign as Cruiserweight Champion was ended at WrestleMania 35 last week - we are guaranteed to see him have classics against the likes of Ali, Balor and Cesaro.

After being neglected towards WrestleMania, SmackDown's women's division seems to have been given a huge boost.

No less than five superstars have joined the ranks, with Bayley being the most notable addition, confirming her split from the potentially-departing Sasha Banks in the process.

She is joined by Ember Moon, Mickie James and Liv Morgan, with the Riott Squad seemingly no longer a thing, and Kairi Sane has made the jump to the main roster from NXT as she was revealed to be part of the team Paige was bringing to SmackDown alongside Asuka.

One aspect of SmackDown that seems to have been weakened though is their tag team division. The Usos have been lost to Raw and The Bar seem to have quietly disbanded, but Otis and Tucker of Heavy Machinery have now found their home on Tuesdays.

With the rosters now shaken-up to their very core, who do you think has gotten the best deal - Raw or SmackDown? Let us know in the comments!
