So, aside from the fitting flavor of the times, sadly, I think Quarantine Field is a Mythic that looks like an uncommon, plays like a Mythic, and fits a common person's budget
Now I love my Siona deck, but there's times where either it's too strong for the table or I just want to win with the deck using other finishers
Proliferate being around helps make this card a lot betterespecially because most players are going to pick the three-mana mode
And thats not to mention the fact that blue can interact on the stack and counter those creatures before they even come into play, or bounce them back to hand when they threaten to attack or combo
Then as your vehicles deal combat damage to your foes, you exile that many cards from their library and you can play them, although there is no mana-washing here, so in a mono-Blue deck you might find it rough to cast non-Blue, non-colorless cards
