3 card packs pokemon TCG Booster Pack: Sword & Shield and Ceruledge — all exclusive to this release and unlikely to see an international print Sun & Moon: Unified Minds

With two colors, you'll be able to cast both colors of spells in most games (not all games, but what most players would consider "an acceptably high" portion of games)

The main reason I prefer Inversion is for its rare card type which can boost a couple of other cards nicely

You want your creatures to have gravity that forces your opponent to pause on advancing their plans to interact with your creature and Exhaust is mechanic that creates that gravity

Besides having an excellent hp and a move that does 100 damage, I wouldn't use this card in a deck because it just isn't effective with the amount of energy required with this card
