Special Summon from your Extra Deck, 1 "Number" monster that has a number between "1" and "100" in its name
As a way to just up your sacrifice potential this is poor
If your deck's key engine is a 4cmc commander like Kaalia of the Vast, for example, then you will want to run ramp cards that can get her out faster, which means ramp that is between 0-2cmc so you can cast Kaalia on turn 3 or earlier instead of her usual turn 4
The largest act of defiance of this trope is Siegfried Schrder, who went so far as to hack the Kaiba Corp card database to recognize an illegal card, and reprogrammed its effect to be ridiculously overpowered (it forces the opponent to discard half their deck each turn, and that's the tip of the iceberg)
But holy hell, let me tell you, Frilled Mystic is absolutely disgusting with Wilderness Reclamation
