Theres a lot of free equipping going on (more on that later) and so I want to get a built-in creature to go with it
One Shantotto is enough to set me down the path, or getting multiple copies of Thunder / Ice Magic, or Sahagin
If they Heros Downfall your creature in response to the spell, the chain is broken and you dont get a replacement Bloodlust
This allows you more flexibility if there isnt a good target for a goad ability, or if it would just make more sense to draw a card or buff your commander
Its such a clean way to manipulate combat, especially in artifact-heavy decks, and they start stirring up trouble as early as turn 2
Casting 4-mana noncreature spells isnt easy: If they dont affect the board in a meaningful way, you often fall too far behind your opponent
