My only suggestion is that the chimeras should be called
"Small Chimera," "Medium Chimera" and "Large Chimera."
"I'd like a Chimera please"
"Would you like that in a meal?"
"yes please"
"Would you like that small, medium, or large?"
"I'll have a large"
"That will be one meld and two trashed cards. Your order will be ready at the window"
