This Saga is very similar in design to History of Benalia that saw a lot of play in past standard seasons. This one focuses on Berserker creatures that have a lot of support in Kaldheim.
Although it has the same little problem like History of Benalia had, when your third chapter doesn't matter much if you don't have an established board, the first two levels are still enough to make this a viable option.
The Berserker tribal players will want all four copies of The Bloodsky Massacre to be in their decks. Also, since most Berserker creatures are either in red or black colors, it means that this Saga will fit right in.
