Some examples: Swords to Plowshares, Teferis Protection, Chaos Warp, Great Train Heist (or other Spree cards, you pay extra costs but can go wild), Akromas Will, Deflecting Swat, Wear/Tear, and my personal favorite, Reprieve
Their spells tend to focus on healing or preventing damage, protecting their allies, and neutralizing an opponent's advantages on the battlefield
Neera, Wild Mage decks are full of cheap cantrips like Ponder because, unlike proper cascade cards, Neera can free-cast anything from the top of the deck regardless of mana value
It's only at the beginning of your combat
Kindred Discovery Drawing cards is good, but paying 5 mana for a do-nothing enchantment isnt ideal
