Let me also get recent sources for context:
Based on the tournament data analysis, Ramp Eldrazi (the current iteration of Eldrazi Tron) shows very similar performance whether running Sire of Seven Deaths or not. Decks without Sire of Seven Deaths achieved a 50.3% winrate across 1,943 entries, while decks including the card posted a 50.6% winrate across 579 entries since the card's release in November 2024.
The difference is minimal at just 0.3 percentage points, suggesting that Sire of Seven Deaths is more of a meta choice than a performance upgrade. About 23% of Ramp Eldrazi pilots have adopted the card, indicating it's seen as a reasonable but not essential inclusion. The large sample sizes (nearly 2,500 total entries) make this comparison statistically meaningful.
The card appears to be filling a specific role in certain meta environments rather than providing a universal power upgrade, which explains why many successful lists continue to operate without it.
