Perfectly balanced, just like Pooh in the card art
Springheart Nantuko While Springheart Nantuko is a great card on its own, allowing you to make a ton of 1/1 creatures, it truly shined as a component of the offensive Nadu, Winged Wisdom deck that led to Nadu's ultimate demise (well, banning anyway)
The closest I could determine was the Semitt Falls, one of the game's first true dungeons and the only one I could find that had a clear waterfall in it (obviously), even though it lacked the crystalline formations on the walls
Battle Screech 4 This is a little hard to abuse
Diamond Weapon Diamond Weapon is a surprising legendary, but should often cost closer to 5 or 6 mana for a beefy 8/8 reach immune to combat damage hampered only by a lack of trample
Papalymo Totolymo* Papalymo here is an interesting spellslinger creature in WB, and would work well with a token focused deck, especially with an aristocrats theme
