mtg cards that let you cast spells from graveyard can be Magus of the Will Conduit of Worlds

There exist multiple decks playing Urzas Saga, the most popular being Affinity, Amulet Titan and Hammer Time, and Force of Vigor can regularly destroy two permanents for zero mana in these matchups

Dont forget that Azula is blue, so you can flicker it for more card advantage and removal

I especially like that you have so much control over the text box and I think it just looks more like a Magic card than Cardsmith creations

It's a pretty common trope in fantasy media and especially in D&D to have monstrous, witchy hags as villains, and I like that the Brine Hag curses every creature that causes her death into having their statistics reduced to 0/2

The elemental tokens easily multiply ETB effects and tacking Pyroclasm onto another effect can be game breaking
