I counter a spell using Summoner’s Bane, creating a 2/2 Illusion token. Because Summoner’s Bane doesn’t specify a name for the token, both its name and creature type are “Illusion.”
Later, I cast Clone. When it resolves, I choose to make it a copy of my 2/2 Illusion. Its name is “Illusion,” too.
Finally, I cast Mask of the Mimic targeting Clone. I search my library for a card named “Illusion” …
… and put this split instant card onto the battlefield.
Happy April Fools day!
