:lol: This is my first go at a special Monster. So here's the information:
How they work:
Split Monsters can only be Split Summoned, which is where you tribute monsters you control, then divide their total levels by two to equal the Split Monster's Cost (Level, Rank, whatever). They go in-between two monster spaces, and they take up two slots. They can have two sets of ATK and DEF, one for each mode. They also have two Attributes and types, again for each mode. The Type, Attribute, ATK and DEF on the right side is Mode 1, and the left side is Mode 2. Their Mode can be changed during your Main Phase instead of Normal Summoning, similar to Pendulum Monsters. When it would be destroyed or sent to the graveyard (Including tributing), it is just changed to the opposite Mode, and can't be changed back unless its re-summoned. It basically would act as if that half was removed. Then when its destroyed again, it is sent to the Graveyard.
Other than being a shield, some Split Monsters will have different effects based on the mode they are in. They also are useful for summoning other monster like Synchros, but they can't be used for XYZ.
(This one does not have a Split effect. I know, I am trying to make it work while also fitting into the card space given.)
Any suggestions are appreciated!!! These are not the final workings.
