But as a card most at home in the sideboard, Negates mana efficiency is perfect for combo or control match-ups when you need additional stack interaction, and when noncreature spells are exactly what you want to answer
you'll need a way to cast them for an alternative cost or without paying their mana cost, such as by suspending them
This is pretty good in itself but also, it gives vehicles and creatures entering the field a 1/1 counter if they have a mana value four or less
This was pretty disgusting and, as the degenerate I am, I also played this while it was legal
While not repeatable in the same way Time Vault is, Time Walk doesnt require other cards or hoops to jump through to cast
Pay particularly close attention to the commons and uncommons in a set
