After years of playing Magic, your hands get used to the weight and texture of the cards
You'll also probably want to run some birds with flying, so it is easier for you to attack and activate Choco, Seeker of Paradie's ability
When you don't want other things from white and when you can just run power houses like Upheaval/Wildfire instead this situational six drop you have to splash for is not popular
Not only does Stomp give you two damage to use however you see fit, but it also stops damage from being prevented
Planeswalkers are a whole other story
Part of a cycle that features the almost-as-broken Gaea's Cradle and somehow the hilariously unbroken Shivan Gorge, Tolarian Academy taps to make a mana for each artifact you control, which led to decks that would dump their entire hand of cheap artifacts, make a ton of mana by tapping and maybe untapping Tolarian Academy, and then use big card-draw spells like Windfall and Stroke of Genius to refill before eventually milling the opponent out with Stroke of Genius, potentially all on Turn 1
