For one life per turn, Phyrexian Arena will let you draw an extra card every turn
Here's one other bit of flavor: you'll notice on the XIV weapons, the Equipment cards have ability words
I like this a lot more with free-equips and/or with Kassandra
This helps with quickly ramping up the number of cards in your inkwell , making it easier to play the high cost characters like Belle, Mechanic Extraordinaire, who can also be a shift target , as well as Lyle Tiberius Rourke, Crystallized Mercenary, who is not only a key damage dealer , but also pretty darn good at questing
You can also do it to your own creature if you want to activate its Enter the Battlefield effect again
Youll either use your angels to save small creatures or to reanimate a larger one
