even I dont like it that much compared to playing decks preassembled for me
General 300 : Add [mana symbol], even if the text box doesnt actually contain that text or the object has no text box
Najeela, the Blade-Blossom or Urza, Lord High Artificer and deny your opponents the ability to activate their own

The lack of red mana in this theoretical deck puts a limit on the number of Final Fantasy Wizards you can consider, but theres still Venat, Heart of Hydaelyn, who lets you draw a card every time you cast a Legendary card
In any deck that has good EtBs and wants to keep attacking, this can be a real value generator
