The ward cost is very specific, but it fuels your own strategy when an opponent does pay it because they have to discard the exact type of cards you want in their graveyard
Not only do you need the pod and the dork and the things to make that dork cheaper compared to their CMC but you also need a target with the exact CMC +1 of the thing you ditch
While Fire Lord Azula has definitely been leading the charge, shes not the only MTG Avatar card with impressive synergy
Hidden Stockpile 7.5/10 This is a great all round card for these kinds of deck as it so freely keeps up your momentum
While this card's debut placed it relatively on par with its predecessor from Evolving Skies, this Prismatic Evolutions chase card has experienced similar ups and downs
That being said, I would definitely find room for Lightning Greaves, Swiftfoot Boots, Mother of Runes, Giver of Runes, & an abundance of Counterspells
