Im admittedly more interested in running Toph, Earthbending Master in the 99 of other experience commanders, but it can also hurl giant land creatures at an opponent each turn in a mono-green deck
However, I would have thought the protagonist from one of the series best games would be a prime candidate for some tight theming
After drawing your opening hand and putting a Basic Pokmon card face down, the next six cards of your deck are put off to the side face down as "prizes." Each time you knock out one of your opponent's Pokmon, you get a reward: putting one (or more) of your prize cards into your hand
One thing to bear in mind, and which slightly complicates matters, is that you may still use an older or otherwise illegal card, as long as it has the same name and printed abilities as one which is currently legal
[/spoiler] [spoiler=Number C9: Chaos Dyson Sphere] 3 Level 10 monsters At the start of the Damage Step, if this card battles an opponent's monster: You can attach that monster to this card as a face-up Xyz Material
Pain and shocklands are similar in that they both cost you life to fully utilize
