[Trigger] Help with tower combination

[darkreapers]

hi i have done a tower combination trigger, just asking how i can make it better, because right now i am making it do, if 2 towers that can combine r on the field, ur unit gains a research option.

once u click the research it removes a random tower of the same type and places a new tower down. it works fine if there is only 1 type of each, but if there is 2, it gets a bit messy.

so anyone know wat i can do to make it better? i think i would need a new system all together, can u suggestion one for me? or link me to one thats already made.
