This deck is running all five of the "Kindred" spells: Kindred Boon, Kindred Charge, Kindred Discovery, Kindred Dominance, and Kindred Summons
The card is outright banned in Legacy, Commander, and Oathbreaker
This won't be the case for Chalice, which, despite playing only a bit part in the 100-card format, is a staple in Vintage and Legacy and even a strong sideboard card in Modern
By playing Kida, Protector of Atlantis, players buy themselves at least another turn to play more characters and/or use those characters to either gain lore or banish opposing characters
Final Verdict: Sylvan Library gives green decks consistent card selection and an optional advantage
But its hard to deny these lands arent neat, giving us a look at the scenery of Bikini Bottom and pairing well with your Spongebob Commander deck
