23 karat gold mewtwo pokemon card 23K Gold-Plated Trading Limited Edition Colorless Psy Purge (90×) Discard up to 3 Psychic Energy from your Pokémon I have the Mewtwo one,

They go back into your hand, so the best cards to sacrifice are ones with good ETB/LTB abilities, preferably cheap ones

Stitch, Rock Star has a resource cost of 6, attack power of 3 and a defense rating of 5

Its probably that you get to play red cards, which I fundamentally think at the most fun-promoting cards in Commander, augmenting any color or color pair with the juice to get things done with a little chaos and unpredictability thrown in there for good measure

Sword of Feast and Famine already wins me games just from the protection alone, and having a three drop that can double-trigger many on damage effects, like Mask of Memory and Goldvein Pick, can come in clutch, especially when you need to connect to get those triggers

Typically a Green ability, Lure mechanics do well in all colors

There are a few mechanics however that do allow for free spells without being far far too good or plain rubbish
