mtg foundations borderless cards Soulstone Sanctuary You may put any number of permanent cards with mana value X or less from among them onto the battlefield Crystal Barricade - Foundations -

These effects are used incredibly rarely in the format already, so it's neat to have this and you might infrequently see it pop up, but I wouldn't put too much stock in its utility, even if it's better than people will first give it credit for

It was treated like a four-color deck despite not having the usual payoffs like the best format staples and the game quickly turned into an archenemy situation

Until end of turn, it has base power and toughness 10/10 and gains trample, annihilator 2, and haste

You can use it to save stuff from mass removal or targeted, protect something post-bounce, and a lot more

The inside is smooth and they dont easily open up on their own

You literally cant lose with this
