i would like to change male corn snake blizzard for another rat snake

Hello, I am offering a half-year-old male blizzard corn snake, used to frozen pinkies, it comes from parents (pewter 66% het amelano anery x blizzard). Unfortunately, it is not suitable for my planned breeding, as I prefer natural coloring. I'll trade it for one of these snakes
two-spotted snake (E. bimaculata) - regardless of sex
Elaphe climacophora regardless of sex
Z. situla regardless of sex
Black rat snake is best classic
Also possible for 2 young classic natural corn snakes, milk snake or king snake. ONLY IN CZECH REPUBLIC I WONT SEND HIM ANYWHERE
