While other sources of healing have been added to the game, Potion is one of the few Item cards to do so
however, this isnt some random person putting it up for a bunch of cash
A template would include the backgrounds as well as text and icons (cost, type, effect, P/T, etc) usually positioned correctly, so that you have everything you need to use in order to create a card
(Along with any special relationships between them, like "all my Lightning Bolts are next to each other.) When someone riffle shuffles, the reason that works is because they can't keep track of exactly where the cards are going in each shuffle, so they end up ignorant of their final positions
What I do believe might finally be plausible is a Persistent Petitioners deck with Bruvac the Grandiloquent at the helm
Youre already getting more mana from mana dorks and mana rocks from turn 2 onward
