To get a Turn 2 Henzie (and therefore be able to Blitz a creature on Turn 3), you have to run around 12-15 mana dorks, and/or cards like Utopia Sprawl and Elvish Spirit Guide/Simian Spirit Guide
Rograkh enables explosive openings by supporting equipment, sacrifice effects, or damage triggers without taxing mana
On top of that, this has proliferate upside
Thats a lot and yet by leaning into the piggybacking of procrastinating and letting the text be as complex as it needs to, the card was a huge hit
First you need the enemy knight Lezales to spawn with the Pisces sign (so he has worst compatibility with Gafgarion), Item for his secondary skillset, and the ability to use Potions unlocked, and then you need to be able to kill everyone else but Gafgarion and Lezales (which itself requires a ton of luck to do before Lezales dies, especially with killing Agrias)
But my favorite part of this sourcebook is the maps of Theros at the end of the book
