My think:
The main shooter of this team is Persia, The best player of this season. but the most unique one is Margaret. His 'weird' lurking timing and habits are so unique, there is no other Sentinel like him in the world.
He always arrives one step faster than his opponents expect. This can be very fatal for teams that are relatively slow in decision-making and tend to burn time (Especially Japanese teams)
The 2 Sentinels comp based on Ivy's Deadlock skills is also very unique. He is the only player who makes Deadlock's ult useful.
This team's ideas are so unique that their opponents almost always feel unfamiliar. It brings the same advantages as PRX: If you're new to SPG, you can't deal with them.
Everyone is criticizing the short Ascension format, which is actually dangerous enough that much is decided by pure luck, but it could be an opportunity for SPG.
This team's weaknesses are equal to its strengths. Their strangeness is a strength, but because the players are so young, they are not flexible enough to respond effectively when Plan A gets blocked.
Their Bind Deadlock comp was unbeatable in the regular season, to the point where Bleed was used on sight, but they lost 2 out of 2 times in the playoffs. Bind, which was unconditionally selected in the regular season, was not selected first in the playoffs. After losing to DK, the only change SPG made was to change Omen to Astra and They lost even more.
SPGs tend to rely on anomalies. On some maps they can't handle Basic comp. Margaret played only one agent(Cypher) all season. They ban Icebox all the time Because it is not a map that uses Cypher.
Because their mechanics are so excellent, it's not a team that can win just by deceiving the opponent, But it is what it is.
All their strengths and weaknesses are one.
A strange team.
