Monstrous Onslaught deals damage equal to your greatest creature's power across up to X targets — in a green stompy shell, that's frequently five or more damage spread across five creatures, which clears a board for five mana. Ghalta, Primal Hunger sitting at 12 power turns this into a one-sided wrath.

Monstrous Onslaught is a Commander card through and through — the format's larger boards and higher creature counts give you both the targets and the high-power creature needed to make the damage count. In competitive 60-card formats like Modern and Pioneer it's too slow and too conditional; removal that doesn't depend on your own board state is almost always better at five mana. Legacy and Vintage have the same problem compounded by a faster clock. Stick to Commander, where a single fatty makes this read like a lopsided board wipe.
