For now, it's time to learn how to build a sealed deck and play Magic: The Gathering | Marvel's Spider-Man
Sensei's Divining Top can be replaced with Scroll Rack or Crystal Ball, providing alternative ways to manipulate the top of your library and ensure efficient card draw (at the cost of losing some infinite combo potential)
Using it at the right time can completely flip the game, which makes Giratina-VSTAR one of those cards that demanded respect the moment it hits the table
And if you were to hold onto a pack or two (or 10) for yourself, who's to know or care
As a bonus, those nonland permanents cant be regenerated, just to add extra insult to injury
How often do you cast a turn 1 Serum Visions, look at the two cards from scry, and think to yourself, I have no idea if these cards are good or not? You can, and likely should, blame yourself for utilizing your spell poorly, but not using that mana has a cost too and with an instant-speed cantrip, you can make a more informed decision while not wasting that manathe best of both worlds
