Obviously cards like Monastery Mentor and Saheeli, Sublime Artificer are both going to garner different levels of value for this deck, but I also think powerful sorceries like Blasphemous Act, Austere Command, and Karns Temporal Sundering are going to be more valuable when you can break through their timing restrictions
like Mufasa, this isnt a card that youre allowed to play in your Inkwell as a source of Ink, however
Overall, Blastoise ex is a tanky Pokmon with one of the most consistent setups in TCG Pocket
Both stories are valid, but they produce very different market dynamics
Elenda is sort of the Serra Ascendant for the zone, and gives you a very real commander damage win con with enough life and a combat trick like Kaya's Onslaught
The market value of this rare card obviously reflects its legacy
