Giagu 1
I've been looking for a decent combination to run Rex in and I came up with this. The Upgrades are nothing crazy just a bunch of decent bang for your buck weapons. The Support/Events are where this deck really shines, with Rex's ability it allows you to dependably run Defensive Position, Dug in, and High Ground. I don't know how I feel about Hostile Take over it might be better just to run another standard removal. Finally Bendu's Lair was my choice in battleground as with Rex you will never lose control of it and your opponent will never have any benefit from it.
