Compact and Efficient: Once assembled, this corrugated cardboard box measures 15" x 3" x 4 1/8" on the outside and 14 1/8" x 2 3/4" x 3 3/4" on the inside, perfect for maximizing storage space without sacrificing accessibility
If a permanent enters the battlefield under an opponent's control with hexproof, indestructible, protection, shroud, and/or ward after Shay Cormac's first ability resolves, it won't lose that ability until you activate Shay Cormac's first ability again
This works remarkably well with other cards associated with the Lost Zone
The most relevant side of this is as a way of exiling opposing creatures while being a better aggressive threat than both Brutal Cathar and Skyclave Apparition
The reason for this is pretty clear
So I would not recommend using this card at all
