While something like a Dark Ritual will always be better for lower cost Commanders, there are cheap effects worth considering
But as with many things in Magic, the more valid targets an effect has the more costly it often is to cast
Having a competitive Elf deck in Modern would be sweet
You never really get to appreciate when playing against Fact or Fiction how often it sits in hand as an unplayable card while you die to cheap tempo cards
Destined on the stack is still a black instant with a converted mana cost of 2, and Lead on the stack is still a green sorcery with a converted mana cost of 4, but Destined to Lead, any time it's not one or the other, is a black and green instant sorcery with a converted mana cost of 6
Sapphire Coil can replace the work of some of the characters in the starter deck, so you can swap in better ones
