Echo's Improved Magic Initiate

You gain the following benefits. 

Level 2 Spells. Choose a class: bard, cleric, druid, sorcerer, warlock, or wizard. You learn two 2nd-level spells of your choice from that class's spell list. You always have those spells prepared. You can cast them once without a spell slot, and you regain the ability to cast them in that way when you finish a Long Rest. You can also cast the spells using any spell slots you have. Intelligence, Wisdom, or Charisma is your spellcasting ability for this feat’s spells (choose when you select this feat).

Spell Change. Whenever you gain a new level, you can replace one of the spells you chose for this feat with a different spell of the same level from the chosen spell list.
