Thankfully, discarding isnt a major drawback thanks to the strong recursion of Zombies and Graveyard-based abilities
Yargle and Multani is a triple stacker of power, and a Giant Growth away from lethal commander damage
Playing a card for a discard instead of ink is great, since it can hit the field as soon as you have another Diablo in play
For instance, theres so many great cards that reference the Power Plant From R/B/G/Y including Voltorb, Magnemite, and even Zapdos: An obvious one is Mewtwo GX that both references the game, manga, and anime: But my favorite is Dark Dugtrio that reminds me of when you find the broken in house from Team Rocket and find the TM Dig: What about yall
That way, you can be assured that there will always be a fan of that card now and in the future
