The idea we went with was based on the living weapon mechanic, where an Equipment enters, creates a creature token, then attaches itself to that token
This is pretty much an upgrade for every creature in the deck by setting the base power to 4/4, which will make them at minimum 5/5 with the counter
Compared to shroud, which prevents a card from being targeted by any spells or abilities, hexproof allows for more interaction and involvement
For example, Meren of Clan Nel Toth looks at your graveyard on your end step and finds your favorite reanimation target or gives you a gravedigger effect
Even rares usually only cost 0.05 tix, so you can fill a deck with interesting choices
The Explorers of the Deep Commander deck has a preorder price of around $38
