Squee got a new card in Dominaria that played in similar mechanic space
Its said that it helped ancient people defend from a great evil
So whats really cool about location cards is that they actually gain you lore during the ready phase of the turn
Equipment artifacts were first introduced to the game with October 2003's Mirrodin set, and they appeared throughout that block representing a creature's magical weapons and other devices
For example, if you control The Ozolith ("Whenever a creature you control leaves the battlefield, if it had counters on it, put those counters on The Ozolith.") when Sin's last ability resolves, you'll put the appropriate number of each kind of counter onto both The Ozolith and the target creature
So let's make sure we can stay alive a bit more: I'll say it, and I'll say it again: Fog effects are wildly underrated in commander, and it's about time people played more of them
