ADVENTURERS! MtG cards!

You guys haven't even come up with the most obvious idea yet!

"Ha! Gorrilla! Right there!"
Makes Khrima more powerful or something

The Judge
Gold Armored Dude (Forgot his name) when equipped with Flowstone

"There are many Guards in the Castle"
I dunno

"There are many Guards in the Castle" by NPC
Can only be played if the 1st GITC is on the field

"There are many Guards in the Castle" the Movie
Can only be played if GITC 2 is on the field

There are many Guards in the Castle" the Interview
Can only be played if GITC 3 is on the field

As for the effects of the 4 GITC's I don't know
Make them something creative

Lasers!
Does X amount of damage but does X2 damage when Khrima is in play.
"Any job worth doing with one laser is worth doing ith many"

Eternity
Eternion when equipped with a Flowstone

BTW
Drecker-Blue because it kind of goes with his laid back personaity
