Illusion // Reality - Apocalypse (Uncommon) [APC-129]

Illusion // Reality is a split card from the Apocalypse set that offers two options: the blue instant Illusion lets you counter a spell unless its controller pays {1}, while Reality provides a green instant that allows you to search your library for a creature card and put it onto the battlefield. This versatility makes it a flexible choice in control decks, where you can disrupt your opponent's plays or ramp into threats. However, the mana cost can be limiting, as you need specific colours for each half.
