If a card is played face down for some reason, like Guardian Shield-Bearer:
Megamorph 3G (You may cast this card face down as a 2/2 creature for 3. Turn it face up any time for its megamorph cost and put a +1/+1 counter on it.)
When Guardian Shield-Bearer is turned face up, put a +1/+1 counter on another creature you control.
Let's say I play Guardian face down, and then I get a card that says I can put a +1/+1 counter on one of my creatures. I choose to put it on my face-down Guardian to make it a 3/3.
When I turn Guardian up, does it lose the +1/+1 counter, since it is transforming (or rather, morphing) into a new creature? What about enchantments or other things attached to it?
What type of creature is the 2/2 when it is face down? Just a "Creature" type creature?
