This script will try making a barebone clone of a tnp3 tag on to a magic generation1 card.

Arguments:
	-h             : this help
	-l             : list all known toy tokens
	-t <data>      : toytype id, 4hex symbols
	-s <data>      : subtype id, 4hex symbols		
	
	For fun,  try the following subtype id: 
	0612 - Lightcore
	0118 - Series 1
	0138 - Series 2
	0234 - Special
	023c - Special
	0020 - Swapforce
