Unlike almost every other format or game type in MTG, a planar deck such as this one can easily be copied & proxied up to play with your playgroup, as most people won't mind too much, (except maybe your local store owners) Also, due to the fact that Planeschase usually goes hand in hand with casual formats, people are also going to be more lenient, since there isn't a lot of money or worth in the plane cards themselves
Other sacrifice outlets include spells that require sacrificing creatures as one of their costs (Deadly Dispute should be the first card in any sacrifice deck), as well as cards with an enters ability that cares about sacrificing like God-Eternal Bontu
The one difference, and the separate coloring schemes make it patently clear, is that they belong to separate categories
Five are Prismari (red/blue), three are Quandrix (blue/green), there are two each for Silverquill (white/black) and Witherbloom (black/green), and only one for Lorehold (white/red)
