Any deck that features creatures flickering onto the battlefield should include Cathars' Crusade if it can, and the Crusade is part of Jumpstart
For example, since Mangara only has 2 power it can be a strong utility creature to cheat out in Alesha, Who Smiles At Death
A role-player in a Spirits deck, Mausoleum Wanderer fills the all-important one-drop slot
Myriad Leaf Shower, its only attack, causes a base of 30 damage multiplied by how many energy cards are attached to both Ogerpon and the opponent's active Pokmon
While it does have larger decks than something like Standard or Modern would normally have, only needing one of any card when building your Commander deck generally makes the format more affordable, too
Of course, Pokmon can also have some difficult moments that relate to maths, but on the other hand, this is good memory training and improves counting skills
