Equivalent cards (red, mythic/rare, high damage based on opponent’s life or creatures):
1. “Heartless Hidetsugu” — deals massive damage based on life totals.
2. “Vexing Shusher” (Not damage-dealing but difficult to interact with and red-green).
3. “Borborygmos Enraged” — deals damage based on lands, scalable threat.
Reason: No exact equivalents, but these have similar “big damage” or scaling potential in red (with or without green).
