Blue Serum Visions doesn't look like much at first glance, but the fact that it replaces itself while allowing you to manipulate the top of your library makes it a powerful card that is good in all stages of the game
Dropping this on turn 2 is very real with a mana dork start, and suddenly by turn 3, youre already threatening to bring a powerful reanimation target back to life
The earliest example of such a card is Wrath of God all the way back in the first Magic set, Limited Edition Alpha
Your opponents will see the card, force you to activate it one way, then pull out the board wipe when the protection is gone
Not sure if itll work, but Im excited to try it out
