I'll analyze the performance of Belcher decks with and without Step Through in Modern. Let me search for the card and archetype first, then query the database to compare performance.
Now let me query the database to compare the performance of Belcher decks with and without Step Through over the last 60 days:
Let me check if there's any Belcher data in a broader timeframe:
I don't have sufficient tournament data to answer this question.
The database shows only one Belcher entry in the past year (from February 2025), and that single entry went 0-1 without Step Through. This is far too little data to make any meaningful comparison about which version performs better.
Belcher appears to be an extremely low-representation archetype in the Modern tournament data I have access to, which makes statistical analysis of card choices within the deck impossible.

Data from tournaments in the Modern format database (Feb 2024 - Oct 2025). Only 1 Belcher entry found, insufficient for performance comparison.
