Multiply two target creatures (Put a iX/iY creature token onto the battlefield with any colours and creature types that target non-goat creature and target non-insect creature don't have where X is the product of their power and Y is the product of their toughness.)
See Challenge # 073.
Trying to fulfill "design a split card which is a horrible pun" and "design a card with a mechanic called multiply".
OK, this is a bit of an unprintable trainwreck. References to "Go forth and multiply" and the vector calculus/epidemiology joke "What do you get when you cross a mosquito with a mountain climber? You can't, one's a vector and the other's a scalar."
But I couldn't quite manage to make something out of "multiply" I thought would be printed even in an "un" set...
