But the exile makes each of them single use only.

If he didn't need to exile a creature from your GY you could reanimate a ] every turn to make a big board for cheap, or a ] to remove pesky enchantments. The problem with Gyrus though is the double exile clause. This allow you to see more cards and have access to more resources. So for example, if you have a ] and a ] in your GY and uses a ], instead of drawing 2 cards you can choose to put 10 cards in your GY an get both to your hand instead. The idea behind matching gyrus with dredge is to fill your GY fast and get good options to trigger his ability, since he allows your GY to become your second hand. By nature, it uses resources that are very hard for other players to get rid and if well built brings a lot of inevitability to the table, since you can keep bringing your dudes back. GY decks are some of the more powerful casual commanders archetypes.

Gyrus is a dude I've trying to make it work for some time, but I'm never exactly satisfied with it.
