You can see in the original post, though, that even when I was gathering pictures, the Delta Species and Power Keepers holo looks so much better than anything I could find for DF/HP/CG
Invasion was filled with mana fixing cards, other sets had their Rampant Growth effects and even multiple-color unfriendly Odyssey had common lands which could be sacrificed for a third color in a pinch
It was not for sale in any toy stores, Pokemon Center, theme decks, sets, or booster packs
The Temples have shown us that scrying is a powerful ability, and this is better than that while working toward a potentially game-winning ultimate just a few turns later
There's a lot of good ways to do this, ranging from Deranged AssistantDeranged Assistant to add mana and self-mill, to Search for AzcantaSearch for Azcanta for mill (plus some card advantage later down the line), to cantrips like Mental NoteMental Note for more synergistic milling
