Ultimately, this is a draft treat with lots of infamous cards, and plenty of collector's items at the top end
When you have such a potent archetype you are just best off trying to do your thing as reliably as possible and Vial in singleton is not what you call reliable
Its a great top end for the deck, and its also a totally fine play early to sculpt your hand and adapt to what your opponent is throwing at you
Creatures you begin to control later in the turn won't gain any abilities, and the abilities gained won't change if creature cards enter or leave your graveyard after the ability has resolved
When I think Go Wide Counters though, the only decks that come to mind are Green ones
Regal Force At the very least, [c]Regal Force[/c] will draw you a single card when it enters the battlefield, as it counts itself as a green creature
