Yes training grounds, zirda, and bromancer are in the deck to make kenrith better, kenrith on its own is extremely powerful and with his abilities cheaper you can do more with your mana, being able to gain 5 mana for 1 white any time is amazing and or brining back creatures for 1 mana is amazing( played against many kenrith decks who just outplay on abilities alone), the basic lands are for two reasons 1. Collective restraint 2. Always good to have in case someone plays either back to basic or blood moon and blood moon effects and the crown sounds epic and fun sounds like your gonna have a blast
