Since Y'shtola repeatedly damages each opponent, cards that trigger off noncombat damage such as Curiosity, Ophidian Eye, Tandem Lookout, Helm of the Ghastlord, and Sigil of Sleep are powerhouses that quickly take over the game
Many of these cards feel like true playmakers, not just solid inclusions in existing decks, but build-around engines or format-shaping threats
While some enchantments that dont have an effect as they enter the battlefield can often feel underpowered, this one triggers in your end step, so you get a very immediate boost to your power
Goblin decks also have underwhelming card draw as a whole, so Vanquisher's Banner's second effect is vital
Theres literally nothing available anywhere
