#2 Dominik Dijakovic
Dominik Dijakovic has only recently started to become a major part of NXT. However, since his debut, he has been dominant and has not been defeated since he lost to the Velveteen Dream several months ago on NXT (back when Dominik Dijakovic was referred to as Chris Dijak). Since then, he has defeated superstars like Shane Thorne and Marcel Barthel.
He also made it to the quarterfinals of the Worlds Collide tournament. The dominant competitor defeated TJP to make it past the first round before being defeated by the aforementioned Tyler Bate in the quarterfinals. He recently started a feud with Keith Lee over the spirit of competition and had a great match with Lee on NXT that ended in a double count-out.
That feud had to be paused due to an injury suffered by Keith Lee. Dominik Dijakovic does not have to do much during WrestleMania weekend so he should definitely be a part of this match. He can play a role similar to the role that Killian Dain played in the Andre the Giant Memorial Battle Royal during WrestleMania 33.
