The problem is, who dictates the value of this particular format of art
Number Thirteen This actually does cost 6 mana, rough, with no built-in reduction cost
Having a zero-cost energy move would provide some incentive to go first, which would make Baby Pokmon viable in many decks
Wizards' first attempt at a legendary bear was Goreclaw, Terror of Qal Sisma, a great standalone card that doesn't really incentivize you to build a deck full of Grizzly Bears and all the underwhelming variants
Like the Charizard alternative full art card, Lugia V is a competitively viable Pokmon card but why would any player use such a valuable collectible when the standard Lugia V is available for less than $10
Freyalise, Llanowars Fury Freyalise stands out among the best Elf commanders in MTG because shes a planeswalker
