#9: Master Key Prize Card While all the cards weve seen so far are incredibly pricey, at least theyre somewhat in circulation
It offers you a bit of defense by stunning an opposing creature when you get attacked, and with proliferate, its not untapping any time soon
Please note that the listed percentages add up to 200%, because theres two slots
It makes use of several other key cards like Argothian Opportunist that just miss the top 3 commons, as Green is fairly deep here with good commons
While the first ability suggests youd limit this card for more aggressive decks, you can even neutralize a blocker for the benefit of another opponent in a multiplayer format like Commander
For example, Llanowar Tribe, Goreclaw, Terror of Qal Sisma, Steel Leaf Champion, and the like make the most of Ghalta's ability to reduce her cost
